Managing Volume Snapshots

U-Recover can manage the allocation of disk space for volume snapshots.

As the space fills up, the operating system will silently drop the oldest snapshots from the volume.

How to Reserve Space for Volume Snapshots

Click or tap on the tab Create (top). Then click or tap on Manage next to the name of the disk volume. Use your mouse or your finger to drag the slider from left to right to increase the reservation of disk space.

If System Protection is turned on, you can also manage the disk space under the tab Protect. Click on Manage next to the name of the protected disk volume.

The reserved disk space is shared by both Volume Shadow Copy (Previous Version) and System Restore Points.

How much space should I reserve?

U-Tools recommends that you reserve at minimum 50GB or 10% of the volume's capacity, whichever is less. U-Recover will warn you if your reservation is below the recommend minimum.

Increase the space above the minimum to retain more snapshots.

If you are storing Windows System Backup Images on a dedicated disk you should allocate 50% of the backup volume's capacity for snapshots. This allows you to save multiple backups, with the older backups stored in volume snapshots. The number of older backups that will be saved on the backup volume will depend how much space you allocated for volume snapshots on the backup volume.

Only differences between the old backup and the new backup are stored in the volume snapshot. For example, if you allocated 50% of the backup volume for snapshots (recommended), and the most recent backup is larger than 50% of the volume, the deltas for the older backups will be silently dropped to make room for the new backup, starting with the oldest first.

Deleting Volume Snapshots

Proprietary Snapshot Providers Are Not Supported

Note: U-Recover does not manage proprietary (non-Microsoft) volume snapshot storage providers (for example, ShadowProtect). Use the vendor's proprietary management utility.
