ReadyNAS 2100 User Manual Disk space utilization field on the Volume screen shows how much space has been reserved for snapshots. Figure 4-11 After the snapshot is taken, if changes on the volume exceed this reserved space, the snapshot is invalidated and can no longer be used. Note: Changes that occupy space in the reserved snapshot space include new file creation, modifications, and deletions; for instance, any time you delete a 1MB file, the change caused by the deletion uses up 1MB of reserved space. When the snapshot does become invalidated, an e-mail alert is sent and the status reflected on the Snapshot screen. The snapshot is no longer usable at this stage. Resizing Snapshot Space If you are constantly getting snapshot invalidation alerts, you might want to either increase the frequency of the snapshot or consider increasing the reserved snapshot space. To do this, or to eliminate your existing snapshot space (thus increasing your usable volume space), you can specify the snapshot space you want in the Snapshot Space section. Simply select a value from the pull-down menu and click Save. Your snapshot space will be limited to approximately 100GB. Figure 4-12 4-12 v1.0, May 2009 Securing Your Data

v1.0, May 2009
Disk space
utilization field on the Volume screen shows how much space has been reserved for
snapshots.
After the snapshot is taken, if changes on the volume exceed this reserved space, the snapshot is
invalidated and can no longer be used.
When the snapshot does become invalidated, an e-mail alert is sent and the status reflected on the
Snapshot
screen. The snapshot is no longer usable at this stage.
Resizing Snapshot Space
If you are constantly getting snapshot invalidation alerts, you might want to either increase the
frequency of the snapshot or consider increasing the reserved snapshot space. To do this, or to
eliminate your existing snapshot space (thus increasing your usable volume space), you can
specify the snapshot space you want in the Snapshot Space section. Simply select a value from the
pull-down menu and click
Save
. Your snapshot space will be limited to approximately 100GB.

Note:
Changes that occupy space in the reserved snapshot space include new file
creation, modifications, and deletions; for instance, any time you delete a 1MB file,
the change caused by the deletion uses up 1MB of reserved space.
