Note:
Changing the values for the cache size can result in cache files that exceed the maximum
cache file based on the current granule size. If the limit is exceeded "out of memory" notices appear
in the event log and the WebUI status page when the first snapshot utilizing that cache file is taken.
The snapshot will fail to create but the cache file is built regardless. It is important to reduce the
cache file size via the above screen or clean the cache files prior to the restart of the NAS system if
an oversized cache file is created.
Warning threshold reached when
This option defines the percentage of cache space which, when consumed, will trigger warning
messages to the system event log.
Begin deleting images when
This option defines the percentage of cache space which, when consumed, will trigger the
automatic deletion of the oldest snapshot on the system. Automatic snapshot deletions are
recorded in the system log.
Cache size
This option specifies the amount of space allocated to the cache file. Increasing this value will
allow more and larger snapshots to be maintained. Make sure that adequate space is available
on the drive where snapshots are stored.
