How to Create Sun StorEdge File Checkpoints

About Checkpoints

A checkpoint is a virtual read-only copy of a primary file volume. The file volume remains in read/write operation. However, all of the data existing at the time you created the checkpoint is still available. You can use a checkpoint to retrieve files that you have mistakenly modified or deleted and to stabilize backups.

Remember that a checkpoint is a virtual, or imaginary, copy of the file volume. It is not an online backup. If the file volume is lost, so are all of the checkpoints.

Note – If your users create or modify many files, the system may require a large amount of storage to retain multiple checkpoint sets of older file versions. The more checkpoints you create, the more it effect it may have on system performance.

Scheduling Checkpoints

The Schedule Checkpoints panel displays the current checkpoint schedule and lets you add, edit, and remove scheduled checkpoints. For each scheduled checkpoint, you can see the file volume name, a description, the scheduled time(s) and day(s), and the amount of time the system will keep the checkpoint. The keep time is the number of days plus the number of hours before the checkpoint is automatically deleted.
