3.3.5 Snapshot Files
An Exascale snapshot is a thinly-provisioned read-only point-in-time copy of a file. The source file for a snapshot can be a regular file, a file clone, or another snapshot. Exascale uses redirect-on-write techniques to create and maintain snapshots very quickly and space-efficiently.
To snapshot a file or group of files, use the ESCLI snapshotfile
command.
All snapshots created in the same operation are point-in-time consistent, and all files in a snapshot operation must be in the same vault.
After creation, snapshots are generally managed using the same commands
and procedures that are used for other files. For example, you can use the
rmfile
command to delete a snapshot.
