6.5 HP StoreAll OS CLI Reference Guide

ibrix_snap
Manages file system snapshots.
Description
The StoreAll software snapshot feature captures a point-in-time copy of a file system or directory
for online backup purposes and simplifies recovery of files from accidental deletion. Software
snapshots can be taken of the entire file system or selected directories. Users can access the file
system or directory as it appeared at the instant of the snapshot.
Before taking snapshots of a file system or directory, you will need to enable the directory tree for
snapshots. This directory tree is also called a snap tree. You can then define a schedule for taking
periodic snapshots of the snap tree, and you can also take on-demand snapshots. (Snapshot
schedules can be defined only on the GUI.)
Scheduled snapshots are deleted automatically according to the retention schedule specified for
the snapshot tree; however you can delete a snapshot manually if necessary. You also need to
delete on-demand snapshots manually. Deleting a snapshot does not free the file system space that
was used by the snapshot; you will need to reclaim the space using the GUI or the
ibrix_snapreclamation command.
IMPORTANT: Before deleting a directory that contains snapshots, take these steps:
• Delete the snapshots (use ibrix_snap).
• Reclaim the file system space used by the snapshots (use ibrix_snapreclamation).
• Remove snapshot authorization for the snap tree (use ibrix_snap).
