Using vStor Autosnapshot
AutoSnapshot is a powerful feature in vStor that allows backup administrators to automatically create snapshots of volumes based on predefined schedules or in response to significant content changes. This ensures that backups always include some level of immutability and can be easily restored in case of data loss or corruption.
Enabling AutoSnapshot
To enable AutoSnapshot for a volume:
Navigate to the Storage tab and click on the name of the desired volume.
In the detailed view, locate the AutoSnapshot section and click the Enable button.
In the Enable AutoSnapshot dialog, configure the following settings:
AutoSnapshot Mode
Choose between two modes:
Smart Detection: Automatically detects changes in volume content and triggers snapshots.
Select either percentage-based or size-based detection.
For percentage-based, specify the threshold for data change.
For size-based, specify the size threshold and unit (MB, GB, TB).
Scheduled AutoSnapshot: Create snapshots based on a predefined schedule.
Choose from interval (1 minute to 12 hours), weekly, or monthly schedules.
For weekly, specify days of the week and time.
For monthly, specify months, days, and time.
After selecting the appropriate mode and customizing the setting, click Enable AutoSnapshot. AutoSnapshot settings will now be visible in the volume view.
Snapshot Limit
Specify the maximum number of snapshots to retain (up to 1000). When this limit is exceeded, the oldest unprotected snapshots are automatically deleted.
Attention! Protected snapshots are not counted towards the snapshot limit.
Managing AutoSnapshot Settings
After enabling AutoSnapshot, you can manage its settings:
Edit: Modify the AutoSnapshot configuration by clicking the Edit button.
Remove: Disable AutoSnapshot by clicking the Remove button.
By leveraging vStor's AutoSnapshot feature, you can enhance your data protection strategy, ensuring more frequent and reliable recovery points for your volumes.
