You may need to manually delete some previous snapshots to make more space. If you
still cannot take the snapshot you may need to recreate the volume with a larger amount of
space reserved for snapshots.
• You can also check the logs on the NSA to find out the reason why the snapshot failed.
• A snapshot must be done on a complete volume. Check that the volume is not down,
locked, or degraded. If it is, then see Section 12.2 on page 249.
V The snapshot or backup does not run at the time configured.
• Check that the correct time is configured on the NSA.
• Check that the NSA is able to access the time server from which it gets the time; see
Chapter 5 on page 121.
