Use Buffer

Uses the Use Buffer option. Files will be copied to the DS-Client Buffer (i.e. as fast as possible for the given server and LAN speed). This will free up the backup source as fast as possible. Then the DS-Client will send the files from the DS-Client buffer to the DS-System.

Detailed log

Records all files that are backed up.

Stop on errors

Sets an error limit, at which a backup will be stopped. Enter the maximum number of errors in the Stop on Errors box to the right.

Start at

Leave this box blank to start the demand backup immediately. Enter a time, if you wish to delay starting the demand backup until the time specified.

Instant Recovery

If selected, this backup set will send a copy of the backup data to the configured instant recovery location connected to the DS-Client.

Verify signature for unchanged files

DS-Client reads the digital signature from the latest online generation of each unchanged file and compares it with the digital signature that was generated from the current source file. If the signatures do not match, DS-Client will backup the file again in the same backup session.

WARNING: Selecting this option will slow down the demand backup performance because the unchanged files that are normally skipped by a backup must be processed.

Backup as POSIX

 

PreScan

Performs a PreScan of all files in the backup set to estimate a time for completion of the backup.

Try deny write

Attempt to open backup file in 'Deny Write' mode. If this fails (because the file is already open), place the backup file in 'Allow Write' mode.

Deny write

This mode prevents any other process from writing to the backup file, while the DS-Client has it open. DS-Client will not back up the file, if another process has already opened it for write. (You can, however, instruct the DS-Client to retry backing up the open file.)

Prevent write

Attempt to open backup file in 'Deny Write' mode. If this fails (because the file is already open), then open in Allow Write mode and lock the file, thereby preventing any process from writing to the file. This ensures that the most recent version of the file is backed up.

Allow write

Allow another process to read/write to the backup file (no restrictions). Since other applications can write to the file while it is being backed up, this can affect file consistency.

Retry times

Specifies the number of times you want the DS-Client to attempt to backup the file. (Maximum of 10 retries).

Retry intervals

Specifies the interval between retries. (Maximum of 999 seconds).

Backup data in Remote Storage

Backup all data on remote media. Some Windows operating systems have the functionality to migrate infrequently accessed data from the local hard drive to directly attached tape libraries. The local disk usage is reduced by replacing the file with a link (shortcut). If disabled, only the link (shortcut file) will be backed up.

Backup Single Instance Store file data

Backup each instance of a file separately. Some Windows operating systems have an optional service 'Single Instance Store' to handle multiple copies of the same file on the computer. Local disk usage is reduced by placing one copy of the file in the Single Instance Store, with links (shortcuts) in all associated directories. If disabled, only the link will be backed up. If you have activated the Single Instance Store Service, check this option.

Follow junction point

Junction points are links to other directories. If this option is enabled, all data in the directory referenced by the junction point will be backed up. If disabled, only links to the directory will be backed up (not the data within the directory).

Note: Functionality for discontinued backup sets might still work, even though they are no longer officially supported.

Default policy

Enforce perform

This option allows you to over-ride the default configuration for this demand backup only.
