Use Snapshots
If you back up a large share while users are still editing files on it, you might end up with a
backup that is inconsistent and unusable. For example, if a user moves a file that has not
been backed up into a folder that has already been backed up, that file will not appear in the
backup and will be lost. You can schedule the backup to occur when no one is accessing the
share, but if that is not possible, you can use a snapshot.
A snapshot is a read-only copy of the volume’s files as they were at a specific time. When
users change files after that time, information about those changes is stored in a special area
on your system’s volume. When users access the share, the ReadyNAS system merges
information from the snapshot with information about changes on the fly and serves
up-to-date data.
A ReadyNAS system serves data more slowly when it is keeping a snapshot, so you might
want to create snapshot of a volume only when you are backing it up.
When creating the backup job for a snapshot, you need to select the name of the snapshot
as the source. To do that, you need to create a snapshot before you create the back up job,
as described in
Create a Snapshot Now
on page
88. The name of a share’s snapshot is the
share’s name plus “-snap.” For example, the snapshot for “media” is “media-snap.”
If the amount of space needed for the changes surpasses the size of the reserved space, the
volume snapshot expires. So, when you create a snapshot schedule, be sure the snapshot is
available long enough for the backup job to finish.
Set Up a Snapshot Schedule
You can use FrontView to set up a snapshot schedule.
To set up a snapshot schedule:
1.
From the FrontView main menu, select
Volumes > Volume Settings
.
2.
Click the Snapshot tab.
If FrontView does not display a Snapshot tab, your volume is not set up for snapshots.
3.
In the Snapshot schedule pane, set the schedule for taking snapshots.
Ensure that the snapshot schedule overlaps the backup schedule.
To give you enough time to create a snapshot before its backup begins, snapshots start
on the hour and backups start at 5 minutes past the hour.
