Synchronizing a backup set
Each backup set has a backup log table in the DS-Client database that contains the following details:
• What is backed up.
• Attributes of what is backed up (date, time, size).
• Master/delta generations (file or block signatures).
For various reasons, such as an interrupted backup session or lost connection before confirmation, the backup log can fall out of synchronization with the DS-System online storage. If this occurs, a Normal synchronization is automatically run during the next Weekly Admin process or scheduled backup.
You can perform the following types of backup set synchronizations:
• Normal: Compares the DS-Client database backup log with the DS-System's online storage, and updates where required.
• Check only (on-demand only): Performs a check of only the synchronization between the DS-Client's backup log and the DS-System online storage. This only identifies if inconsistencies exist, however no corrective action is taken.
• DS-System based (on-demand only): Updates the entire DS-Client database backup log with the DS-System online storage.
By default, scheduled Weekly Admin performs synchronization only on backup sets marked ‘Out of Sync’. To have it perform synchronization on all backup sets, configure the
AdminSkipSync parameter in the DS-Client advanced configuration (see
“Configuring the advanced settings”).
To synchronize a backup set on-demand:
1. Browse the Backup Sets tree and select the backup set you want.
2. On the Sets menu, click Backup Sets, and then Synchronize.
3. In the Select Synchronization Options dialog box, select the synchronization method, and then click Synchronize.
4. Check the Activity Log and Event log for the synchronization process for any errors.
