BigMasterSize

During backup, DS-Client maintains additional meta-data for files larger than this size (in MB), until the new generation backs up to DS-System successfully. This overhead is balanced by the benefit of reducing the chance of re-sending the next generation as a master in case the backup experiences unexpected failures.

CacheSQLiteFile

Caches the SQLite database file to improve speed.

DBBulkOptions

Configures one of the following database bulk insert options:

The selection takes effect immediately.

DBConnections

How many database connections to create when the DS-Client service starts.

DBSerializableRepeats

Number of times DS-Client will retry a PostgreSQL serializable transaction if it fails.

DefaultCompression

Configures ZLIB compression level:

0 = no compression (faster)

9 = maximum compression (slower)

DeltaThreads

Number of delta threads per backup thread.

0 = Delta backup is singled threaded.

1 = A single thread does compression / encryption, but it is separated from I/O thread.

> 1 = Delta process is multi-threaded.

Note: For Grid DS-Clients, this parameter can be applied globally or to individual leaf nodes.

DeltaThreadsFS

Number of delta threads for file system backups. If you only back up big files, increasing this can improve speed. For backup of small files, the default is usually sufficient.

Note: For Grid DS-Clients, this parameter can be applied globally or to individual leaf nodes.

DSClientPerformCopyFromSnapshot

For Microsoft SQL Server (VSS-aware) backup sets with Nimble Storage integration. How the data copy from the snapshot is triggered.

EncryptedLocalData

Encrypt the data saved in the Local Storage for Local Storage backup sets and Local-Only backup sets using the DS-Client’s Private Key.

ExchangeOnlineRestoreBatchSize

Configure buffering when DS-Client restores Exchange data for Cloud (Microsoft Office 365) or Microsoft Exchange Server EWS backup sets to a Cloud destination.

To specify the maximum number of items that can be cached to buffer, enter a value between 1 and 1000.

 

When this parameter is set to 1, DS-Client will upload data one item at a time to the Cloud destination.

 

When this parameter is set to 2 or greater, buffering is enabled. DS-Client will cache the data to buffer up to the number of items specified in this parameter and then upload the data to the Cloud destination.

FileReadBufferSize

The internal buffer size (in KB) allocated for reading a file during the backup process.

MasterGenerations

Generates a full master file on DS-System after this number of generations. Used with the SendFullMaster parameter.

MaxCacheCopySessions

Maximum concurrent activities supported by DS-Client. Increase if hardware can support additional processing.

Note: For Grid DS-Clients, this parameter can be applied globally or to individual leaf nodes.

MaxDeltaSize

Maximum file size (in GB) for delta algorithm to apply. The bigger the size, the more memory that is needed for delta processing.

MaxPendingIOPerFile

Maximum pending I/O requests for backup or restore of a single file. Increasing this value can improve backup / restore speed if the target storage has very good parallelism (ability to perform simultaneous I/O requests). This option is for high performance environments where you can test the disk I/O.

Important: Increasing this value too much can cause performance to slow.

MaxRestoreReadThreads

Maximum number of read threads on DS-System side for a restore process.

Note: For Grid DS-Clients, this parameter can be applied globally or to individual leaf nodes.

MaxRestoreThreads

Maximum number of threads for a restore process.

Note: For Grid DS-Clients, this parameter can be applied globally or to individual leaf nodes.

MaxSessionCheck

Determines when the MaxSessions parameter applies.

MaxSessions

Maximum concurrent activities supported by DS-Client. Increase only if your hardware can support additional processing.

For Grid DS-Clients, this parameter also refers to the Task Limit (On the Grid menu, point to Grid Status, and then click the List tab for each node).

Note: For Grid DS-Clients, this parameter can be applied globally or to individual leaf nodes.

MaxThreads

Maximum number of threads for each backup activity. Increase only if your hardware can support additional processing.

Note: For Grid DS-Clients, this parameter can be applied globally or to individual leaf nodes.

MaxThreadsMLR

Maximum number of threads for each DS-MLR backup activity. Increase only if your hardware can support additional processing.

Note: For Grid DS-Clients, this parameter can be applied globally or to individual leaf nodes.

MinDeltaGen

The minimum number of online generations required to process files as deltas.

MinDeltaSize

Minimum file size (in KB) for delta algorithm to apply.

RestoreCacheBufferSize

Internal buffer size (in MB) for caching restore data. Increasing this value can improve the restore performance.

SalesforceExtractThreads

For Backup from the Cloud (Salesforce.com) backup sets only.

Number of threads to use when extracting data from Salesforce.com.

SalesforceRestoreSysTables

For Backup from the Cloud (Salesforce.com) backup sets only.

Attempt to recover Salesforce system tables when performing restore.

SalesforceUseBulkApi

For Backup from the Cloud (Salesforce.com) backup sets only.

Use the Salesforce “BULK API” protocol to retrieve data. If off, records are read row-by-row, which can significantly increase the number of API calls used.

SendFullMaster

Backups always send a full master (instead of an incremental delta).

SkipCompressionOnCompressedFiles

Skips compression on the following types of compressed files: pk, zip, gif, png, Microsoft Cabinet Files, gzip, win, jpeg & jfif.

SortMethod

Sort algorithm used to sort internal list.

SQLQueriesUseIndexHints

Applicable for SQL Server databases only.

Use index hints in SQL queries to the DS-Client database.

StatisticalCpuUsage

Limits the DS-Client's consumption of the computer's CPU during statistical backups to this percentage.
