Configuring the DS-System : Configuring the advanced settings
 
Configuring the advanced settings
IMPORTANT:  Changing the advanced settings can significantly affect DS-System behavior and performance.
The advanced configuration settings contain a list of parameters that determine how the DS-System behaves. The default settings are sufficient to run a typical DS-System. However advanced users with specific requirements can change these settings.
NOTE:  Some of these parameters are used to apply a consistent setting across all nodes in an N+1 configuration because individual nodes might have different configurations in their dssys.cfg file. For more information see: “Updating the DS-System configuration file parameters”.
To configure the advanced settings:
1. On the Setup menu, click Advanced Configuration.
2. In the list, select the parameter you want to configure and click Edit.
3. In the Value box, enter the value for the parameter.
4. Click OK.
The list of parameters and their settings are as follows:

Specifies how many days of database dumps to retain in the primary storage dump sub-folder. Note the storage implications.
Default: 2
Range: 1-10,000
DBDumpEnd
Specifies the end hour for the database backup window. If this value is less than the DBDumpStart value, the end hour occurs the next day.
Windows:
Default: 23
Range: 0-23
Linux
Default: 17
Range: 0-23
DBDumpMethod
Specifies the type of DS-System database backup. The DS-System performs a database backup (dump) during the dump window specified by the DBDumpStart and DBDumpEnd parameters.
Windows:
0 = differential, DS-System performs a full database dump (by default at midnight - 00:00) every day and a differential backup of its database every hour. The differential database backup is appended to the full dump file. If a differential backup fails for any reason, then a full database dump will be performed immediately following that failure.
1 = full, DS-System performs a full database dump once a day (by default at midnight - 00:00) and it does not perform any other differential backups for that day.
Linux:
0 = custom, DS-System dumps the database in TAR format, compressed.
1 = tar, DS-System dumps the database in TAR format, uncompressed.
2 = plain text, DS-System dumps the database in plain text format.
DBDumpPath
Specifies the location where the DS-System database dump will be written. This can be any path accessible by the DS-System. The SQL service account must have read/write permission for the dump location. Note the potential space requirements for the dump location.
DBDumpStart
Specifies the start hour for the database backup window. For differential backups, the start time is also when the full database dump occurs (in any 24-hour period).
Windows:
Default: 0
Range: 0-23
Linux:
Default: 8
Range: 0-23
DefaultHardwareResetTimer
Specifies the amount of time (in minutes) that is permitted for the DS-Client to connect and perform a hardware registration activity.
Default: 5
Range: 1-10,080
DefaultTrashDays
Specifies the minimum number of days that a file must stay in an extensible storage location's trash folder before it qualifies for removal by the empty trash process.
Default: 7
Range: 0-99
Note: If you specify a value of 0, the data will not be permanently deleted until midnight the following day.
DeltaCheckOption
Specifies whether to perform validation of delta reconstruction indexes during the Autonomic Healing process.
Default: 0
Range: 0-2
0 = validate delta index only
1 = skip validation of delta indexes
2 = validate delta index and check delta block checksum (this will significantly increase processing time because every data block is checked)
DirectorMode
(N+1 specific)
Specifies how the DS-Directory operates in an N+1 DS-System.
0 = Dedicated DS-Director, will not accept DS-Client connections
1 = DS-Director works as a normal DS-System to accept DS-Client connections
Note: if the number of nodes is > 10, the default is 0. Otherwise the default is 1.
DirScanLimit 1
Specifies how many directories can be opened at the same time by a DS-Client synchronization process to limit DS-System I/O.
Default: 5
Range: 1-1000
DirStoreSafeMode
Determines how the DS-System saves directory metadata. If this parameter is enabled, the DS-System saves the directory descriptor information in two locations:
 
Individual _dirdesc files in the corresponding directories where the backed up data appears.
Consolidated _dir_store file from all directories in a backup set.
 
When the information is required, DS-System searches the _dir_store file first and then the specific _dirdesc files.
 
If this parameter is disabled, DS-System saves the directory descriptor information only in the consolidated _dir_store file from all directories in a backup set. DS-System no longer updates individual _dirdesc files in each backup set directory.
 
The “_dirdesc” files are created by the DS-System in the online storage and hold metadata for the backed up data in the corresponding folder where they appear.
 
There are three levels of _dirdesc files for the DS-System:
Backup set level — These _dirdesc files contain information about the backup set.
Share level — These _dirdesc files contain information about the share.
Directory level — These _dirdesc files contain information about the directory.
All activities running on the DS-System access the backup set level _dirdesc files. The restore and validation restore activities do not access the _dirdesc files at the directory level. All other activities require all the _dirdesc files (at all levels) to complete.
 
DS-System verifies the validity of a _dirdesc file every time it is accessed. Each _dirdesc file contains a file signature. When the file is opened, the DS-System calculates the file signature and compares it to the one that it is stored inside the file. If a _dirdesc file is found to be corrupted or missing entirely, the following actions are taken by the DS-System:
When autonomic healing and System Admin detect a _dirdesc file corruption, an error is reported in the DS-System Event Log for that activity and that directory is skipped by the autonomic healing or System Admin process.
When backup activities are running, the _dirdesc file is automatically overwritten without checking its validity.
DirStoreSafeMode
(continued)
When synchronization activities are running, the corrupted or missing _dirdesc file is replaced with information received from the DS-Client. If DS-Client cannot provide this information, the DS-System will create a _dirdesc file with alternate file information in the form:
RECOVER_DIR_<dir_id>
 
Where <dir_id> is the directory ID number, to ensure a unique name.
 
0 = Off
1 = On (default)
DirStoreVacuum
Specifies the threshold percentage that must be reached before the DS-System cleans up empty space in the _dir_store file for backup sets. Each _dir_store file for each backup set is assessed separately.
 
Default: 5 (e.g. 5%)
Range: 0-100
DisasterRecoveryMode 1
Specifies if DS-System should run in normal or disaster recovery mode.
 
In the event of a hardware failure on a DS-System configured with multiple storage locations, only the affected storage location(s) need to be restored. However, because of the interdependencies and the links between storage locations, DS-System must be configured to run in Disaster Recovery mode to rebuild the storage links for every backup set. When DS-System is started in Disaster Recovery mode, no activities are allowed until scanning and recovery of all backup set directories from all storage locations is finished. If the storage location is the primary one - holding the online storage root - you must configure the new storage location with the same absolute path as the original one. Preserving the exact absolute path is recommended even when recovering a secondary location, although it is not compulsory. If the replacement storage location has a different path than the original one, all links from the other storage locations (pointing to the replaced one) must be recreated.
 
Important: This parameter should only be used in case of an actual failure in the DS-System’s extensible storage.
 
0 = Off, Run DS-System in normal mode (default)
1 = On, Run DS-System in disaster recovery mode
DSSysGroup 1
Allows configuration of DS-System groups for replication.
0 = Off
1 = On
EmerPMFreq
SSpecifies the frequency (in hours) that emergency messages will be written to the Event Log.pecifies the emergency message frequency (in hours).
Default: 1
Range: 1-24
ExcludeRecycleDelta 1
Specifies if recycled delta generations are included or excluded from calculations of stored size.
0 (Off) = DS-System includes recycled delta generations.
1 (On) = DS-System excludes recycled delta generations.
FailBackupOnBLMError
Specifies what happens if the movement of data to the BLM Archiver fails for backup sets configured with the BLM (Infinite Generations) option.
0 (Off) = The backup ignores the BLM error.
1 (On) = The backup of that specific generation will fail.
FileStoreCache
Specifies the number of consolidated FileStores that can be open at the same time. By caching FileStores, DS-System reduces the I/O overhead if the process needs to access the same FileStore multiple times.
 
This applies to the backup, disc/tape write-to-buffer, autonomic healing, BLM Archiver, and replication processes.
 
Default: 2
Range: 0-100
 
Note: 0 means only the current FileStore is allowed to be open. Higher values require more system resources.
FileStoreVacuum
Specifies the percentage of the total number of deleted files in the FileStore that must be reached before System Admin triggers a Vacuum FileStore process. Each FileStore (in each directory) is assessed separately.
 
Over time, some small files in a FileStore will become obsolete from generation overwriting and delete processes. Due to the FileStore structure, files deleted from the DS-System Online Storage are only marked for deletion; they are not automatically removed from the storage. These files are only removed when the FileStore is vacuumed and the whole FileStore is rewritten to the DS-System online storage. Files marked for deletion in a FileStore are not counted towards billing or other statistics.
Default: 5 (i.e. 5%)
Range: 0-100
FileWriteTrunkSize
Specifies how much data is cached for write operations to online storage. This parameter allows you to optimize write performance.
Default: 32 (KB)
FixDeltaChain
Specifies to fix a long delta chain during the optimization process. This applies if the number of deltas for a file is longer than the value for the Default delta chain length parameter. This applies only to ‘on-demand’ master /delta optimizations triggered from DS-Operator. Automatic optimizations will always fix the delta chain.
0 = Off
1 = On
GrpEncrypt
Specifies if encrypted communication should be used for a DS-System group. All DS-Systems in the group must have the same setting:

Specifies the DS-System group communication port. All DS-Systems in the group must have the same setting:
Default: 0
Range: 0-2,147,483,647
HealingProcess
Specifies how many autonomic healing processes start at once.
Default: 3
Range: 1-256
LibCreateCount 1
Specifies the number of copies of the same content that must be backed up before a library file is created.
Default: 3
Range: 2-10
LicExpireNotif

Default: 7
Range: 1-100
LicNotifFreq
Specifies the notification frequency (in hours) for the license expiration (LicExpireNotif) and license capacity (LicStorageNotif) parameters.
Default: 1
Range: 1-24
LicStorageNotif
Specifies the license storage capacity warning level percentage. The value is divided by 100 to give a percentage (accurate to two decimal places). When available capacity falls below this amount, DS-System sends a notification.
 
For DS-Systems licensed from a DS-License Server RLM, the license capacity notification also applies when available Local Only Storage and VM replication fall below this level. To view the limits, on the Help menu, click About DS-Operator, and then click DS-System Info.
Default: 1000 (e.g. 10% left / 90% used)
Range: 1-10000, default is 1000

Specifies the maximum number of pending requests in the receiving queue. Increasing this number can improve data transfer speeds.
Default: 20
Range: 20-1024
MaxSendingQueueSize 1
Specifies the maximum number of pending requests in the sending queue. Increasing this number may improve data transfer speeds.
Default: 20
Range: 20-1024
MemEmerLevel
If the free memory falls to a level equal or below this level, an emergency notification is sent. The value divided by 100 is the percentage (e.g. 500/100=5%).
Default: 0 (no check performed)
Range: 0-10,000
MemWarnLevel
If the free memory falls to a level equal or below this level, a warning notification is sent. The value divided by 100 is the percentage (e.g. 500/100=5%).
Default: 0 (no check performed)
Range: 0-10,000
MinLibFileSize
Specifies the minimum size (in KB) for library files on the DS-System. Potential library files smaller than this value will be ignored by the common file elimination process.
Default: 32
Range: 32-102,400
MLRCache
Specifies the number of consolidated FileStores that can be open at the same time. By caching FileStores, DS-System reduces the I/O overhead if the process needs to access the same FileStore multiple times.
 
This only applies to backup processes for email level backup sets and will have the most impact on Continuous Data Protection (CDP) email backup sets.
 
Default: 10
Range: 0-100
 
Note: This works best if the value is at least equivalent to the number of folders in the email backup set. This will allow the backup process to keep an open cache for all folders that might receive new CDP emails.
MultiStorage
Specifies if multiple storage locations can be configured on the same volume.
0 (Off) = (Default) Do not allow multiple storage locations on the same volume.
1 (On) = Allow multiple storage locations on the same volume.
NativeSize
Specifies if the DS-System will save the native size information in its “dsset_size” table, which can only be viewed if the database is queried directly.
Native size — size of the latest generation of all data detected on the backup set source as of the last completed backup.
Deleted size — size of the latest generation of all data deleted from the source that is still in the online storage.
Max generations — Largest number of generations configured for a backup set item.
Min generations — Smallest number of generations configured for a backup set item.
Current generations — the largest number of generations stored online for the backup set.
 
Default: 0
Range: 0-2
0 — Disabled. DS-Client will not send native size data to DS-System.
1 — Enabled. DS-Client will send native size. The native size does not include files that are already pushed to BLM Archiver by retention rules. For each backup set, DS-Client calculates and sends the information to DS-System.
2 — Enabled. DS-Client will send native size. The native size includes files that have already been pushed to BLM Archiver by retention rules.
OLEmerLevel
Specifies the emergency notification level for the available space in the online storage based on the following space events configured for extensible storage locations:
Physical space is represented by the Disk Space column. If any location reaches a notification level, a notification is sent.
Logical space is represented by the Used Size column. If all storage locations reach a notification level, a notification is sent.
When reached, DS-System denies all new backup activities, but allows existing backup activities to continue.
 
The percentage is calculated by dividing the value by 100 (e.g. 500/100=5%).
 
Default: 200 (2%)
Range: 1-10,000
OLStopLevel
Specifies the stop notification level for the available space in the online storage based on the following space events configured for extensible storage locations:
Physical space is represented by the Disk Space column. If any location reaches a notification level, a notification is sent.
Logical space is represented by the Used Size column. If all storage locations reach a notification level, a notification is sent.
When reached, DS-System denies all new backup activities and stops all existing backup activities. The DS-System service will continue to run.
 
The percentage is calculated by dividing the value by 100 (e.g. 500/100=5%).
 
Default: 50 (0.5%)
Range: 1-10,000
OLWarnLevel
Specifies the warning notification level for the available space in the online storage based on the following space events configured for extensible storage locations:
Physical space is represented by the Disk Space column. If any location reaches a notification level, a notification is sent.
Logical space is represented by the Used Size column. If all storage locations reach a notification level, a notification is sent.
 
The percentage is calculated by dividing the value by 100 (e.g. 500/100=5%).
 
Default: 500 (5%)
Range: 1-10,000
PubLibSwitch
Configures the global public library switch.
0 (Off) = No public libraries. However, customer and DS-Client libraries can exist.
1 (On) = Allows public libraries (default).
ReadOnly 1
Configures a read-only DS-System.
0 (Off) = Normal DS-System (default)
1 (On) = DS-System will run with read-only storage. It does not allow or perform any activities that alter the storage.
RecoveryLibThreads
Specifies the number of threads used to recover libraries during DS-System disaster recovery if the DisasterRecoveryMode parameter is set to 1.
Default: 4
Range: 1-16
RecoveryProcess
Specifies the number of disaster recovery processes that can start on each DS-System node at the same time. When the disaster recovery process finishes processing a backup set, the DS-Client must perform a DS-System based synchronization. Weekly Admin or scheduled backups initiate this synchronization automatically.
Default: 4
Range: 1-100
RecoveryValidateFile
Enables disaster recovery to perform file level validations. Enabling this option will significantly affect the performance. It is recommended that you perform autonomic healing instead because it has more advanced file level validations.
0 = Off
1 = On
RecycleSwitch
Specifies if delta recycling is enabled. Delta recycling only affects the frequency of master file reconstructions. If On, backups are faster at the expense of storage. If Off, backups are slower due to the greater number of reconstructions.
0 = Off, disable delta recycling
1 = On, enable recycle delta (default)
RemoteVDRMaxSched
Specifies the maximum number of scheduled Remote DS-VDR activities that are allowed to run concurrently. If more are scheduled at the same time, they will be postponed until some that are running complete.
Default: 10
Range: 0-99
RemoteVDRPowerOnPrioDelayDef
Specifies the default delay time (in seconds) for the Power On option if multiple virtual machines are configured for Remote DS-VDR.
Default: 60
Range: 0-3600
RemoteVDRRetry
Specifies the number of times DS-System will attempt to connect to the Remote DS-VDR Tool.
Default: 5
Range: 0-99
RemoteVDRWait
Specifies the amount of time (in minutes) that the DS-System will wait before retrying to connect to the Remote DS-VDR Tool.
Default: 5
Range: 0-99
RepairFromReplication
Specifies how the DS-System will handle corrupted generations discovered by the autonomic healing, System Admin, validation, or system validation processes.
0 = Off - If a corrupted generation is found, the process will delete the file without trying to recover it from the replication DS-System.
1 = On (default)
ReplicationCheck
Specifies the interval (in hours) at which a replication check is performed for shared DS-Clients.
Default: 6
Range: 0-360 (0 = disabled)
ReplicationDelThreads
Specifies the number of delete threads that should be started for replication.
Default: 2
Range: 1-100
ReplicationProcess
Specifies the maximum number of concurrent replication processes on each node. There must be at least two DS-Systems in a replication group. The most common configuration for a replication group consists of one production DS-System (e.g. a standalone DS-System) and one replication DS-System (e.g. an N+1 DS-System). Only a production DS-System receives data from DS-Clients. Replication DS-Systems normally only receive data from a production DS-System in the replication group. A replication DS-System will only send data to other DS-Systems in the group in case of data loss on a DS-System.
 
This parameter is configurable at DS-System level for each DS-System in the replication group. If a DS-System is configured to start n replication activities, that DS-System will only start n replication activities. However, replication activities (either send or receive) can be triggered from other DS-Systems in the replication group. This means you might see more replication activities running than the configured value for a DS-System.
 
Default: 4
Range: 0-100
ReplicationRecvThreads
How many receive threads should be started for replication:
Default: 4
Range: 1-100
ReplicationSendThreads
Specifies the number of send threads that should be started for replication.
Default: 2
Range: 1-100
SkipDBDump
Specifies if the DS-System will skip the database backup (dump).
0 (Off) = (default) The DS-System database is backed up (dumped) based on the DBDumpMethod, DBDumpStart, and DBDumpEnd.
1 (On) = Skips the database backup (dump).
SmallFileCount
Specifies the threshold to consolidate small files (non-master/delta) in the same online storage directory into one large FileStore during System Admin. Consolidation is performed by both the backup process and the System Admin process:
Backup process — new small files are automatically saved to the FileStore.
System Admin process — existing small files are consolidated as their directories are processed by System Admin if they meet the SmallFileCount threshold.
 
This can achieve significant improvements for processes involving backup sets with large quantities of small files in the same directory. The consolidated small files feature works at the directory level on the DS-System online storage. It works on regular files that are smaller than 64 KB (by default). Files larger than 64 KB are usually backed up as master/delta and are not consolidated. However, this depends on the minimum delta size settings on the DS-Client, which is configurable using the MinDeltaSize advanced parameter. For more information, see the DS-Client User Guide.
Default: 10
Range: 0-10,000
Note: 0 means all small files in a directory will be consolidated to the FileStore.
SMTPDebug
Specifies if debug information for the SMTP send message process is logged. This debug information will be saved to the DS-System Event Log, which can help trace problems with the SMTP server used.
0 = Off (default)
1 = On
SyncDRScan
Specifies if a disaster recovery scan is performed during synchronization. This prevents DS-Client from deleting backup sets or files from its database during a synchronization process in the (unlikely) event that the DS-System online storage has extensible storage link issues. The scan verifies (and rebuilds if necessary) the storage links for a backup set.
 
0 (Off) = (default) Disables the scan unless an entire backup set is missing on the DS-System.
1 (On) = Forces a scan during any backup set synchronization from DS-Client. This is more secure, in case of corruptions to the storage links in the DS-System's extensible storage, but will result in a slower synchronization.
SysAdminProcess
Specifies the number of System Admin processes that can start on each DS-System node at the same time.
Default: 1
Range: 1-20
TcpBufferSize
Specifies the buffer size for communication (in bytes).
Default: 34,752 (Windows), 0 (Linux)
Range: 0-34,752,000
Note: A value of 0 uses the default settings from the operating system.
TcpNoDelay
Disables or enables the TCP option TCP_NODELAY. This can be useful in a high latency TCP environment where the round-trip time for messages is slow.
0 = Off
1 = On (default)
TrashSwitch
Configures the trash feature on the DS-System.
If enabled (default), all processes that delete data from the DS-System will move deleted files to the corresponding extensible storage location's trash folder. Data must wait in the trash folder for at least the DefaultTrashDays amount before an empty trash process can permanently remove the data.
If disabled, any data that is deleted from DS-System online storage is permanently removed.
 
0 = Off
1 = On (default)
UseClientSNAP
Uses a third party snapshot for DS-Client BLM point-in-time copy requests to unlock a backup set as quickly as possible.
0 (Off) = DS-System locks a backup set for the duration of the BLM Archiving activity.
1 (On) = DS-System integrates with third-party software to create a snapshot of the required directories. Once the snapshot is created, DS-System unlocks the backup set. The BLM Point-In-Time request will be performed from the snapshot data.
UseSnapshot
Uses a storage snapshot for DS-System snapshot-capable processes. A maximum of one snapshot per minute is taken. DS-System waits 60 seconds from the first process that requests a storage snapshot and queues all other snapshot-capable requests received in that period to use the same snapshot.
0 = Off (default)
1 = On
VADPCfgDevIgnoreList
Specifies the VM configuration parameters to ignore, such as device keys, during an incremental virtual machine restore via Remote DS-VDR. This parameter applies only to VMware VADP backup sets. Device keys are listed in regular expressions.
 
If the Remote DS-VDR Tool detects changes to VM configuration parameters since the previous restore point of a backup set, a full virtual machine restore is performed. If detected changes belong to device keys in the list, an incremental virtual machine restore is performed.
 
A default list is provided. You can add, modify, or remove regular expressions for individual VM configuration parameters in the list as required.
VADPCfgIgnoreList
Specifies the VM configuration parameters to ignore, such as root keys, during an incremental virtual machine restore via Remote DS-VDR. This parameter applies only to VMware VADP backup sets. Root keys are listed in regular expressions.
 
If the Remote DS-VDR Tool detects changes to VM configuration parameters since the previous restore point of a backup set, a full virtual machine restore is performed. If detected changes belong to root keys in the list, an incremental virtual machine restore is performed.
 
A default list is provided. You can add, modify, or remove regular expressions for individual VM configuration parameters in the list as required.
WarnPMFreq
Specifies the warning message frequency (in hours).
Default: 4
Range: 1-24

1 Changes to these parameters require a DS-System restart.
