This option is effective only for Linux operating systems when you back up volumes managed by Linux Logical Volume Manager (LVM). Such volumes are also called logical volumes.
This option defines how to take and to work with a snapshot of a logical volume. Use of snapshots ensures a time-consistent backup of volumes whose data may change during the backup process.
The preset is: Acronis Backup & Recovery 11
Tip: We recommend changing the preset only if you are experiencing problems with backing up logical volumes.
The possible settings are the following:
Acronis Backup & Recovery 11
Acronis Backup & Recovery 11 will use its own mechanism to take the snapshot and to work with it during backup.
Logical volume manager
Acronis Backup & Recovery 11 will use Linux Logical Volume Manager to take the snapshot and to work with it during backup. This way, backing up the volume may be less efficient than when using Acronis’s mechanism.
If the logical volume manager cannot take the snapshot, Acronis Backup & Recovery 11 works as if the Acronis Backup & Recovery 11 setting were selected.
If working with the snapshot fails after taking it, no alternative snapshot is taken. This applies to either setting.
