HP StoreAll Storage - Manual (Page 360)

You must manually delete on-demand snapshots when they are no longer needed.
Determining space used by snapshots
Space used by snapshots counts towards the used capacity of the file system and towards user
quotas. Standard file system space reporting utilities work as follows:
•
The ls and du commands report the size of a file depending on the version you are viewing.
if you are looking at a snapshot, the commands report the size of the file when it was snapped.
If you are looking at the current version, the commands report the current size.
•
The df command reports the total space used in the file system by files and snapshots.
Accessing snapshot directories
Snapshots are stored in a read-only directory named .snapshot located under the directory tree.
For example, snapshots for directory tree /ibfs1/users are stored in the /ibfs1/users/
.snapshot
directory. Each snapshot is a separate directory beneath the .snapshot directory.
Snapshots are named using the ISO 8601 date and time format, plus a custom value. For example,
a snapshot created on June 1, 2011 at 9am will be named 2011-06-01T090000_<name>. For
snapshots created automatically, <name> is hourly, daily, weekly, or monthly, depending
on the snapshot schedule. If you create a snapshot on-demand, you can specify the <name>.
