Backups

P and Q drives

Snapshots of each drive are taken "daily/hourly" (every 6 hours), nightly, and weekly. By adding ~snapshot after the address, the user can see two days worth of daily/hourly snapshots, 6 nights of nightly snapshots, and 2 weeks of weekly snapshots.
Database backups are taken nightly and weekly.
- Full backups are taken once a month with a Level 1 backup two weeks later backing up any changes since the first Full backup that month.
- Incremental backups are nightly and retained for 14 days.
- The first full backup of every month is retained for 3 months.
- The Level 1 backup every month is retained for 3 months.

Restores

For P and Q drive restores, users should be encouraged to use snapshots to recover data lost within the past 14 days. Tip sheets:
For all other restores, a request should be sent to the UIT Client Support Center/UIT DataCenter Operations.

Restores for Windows computers:

------------------------------------------------------------------------------------------
1. In Windows Explorer, display the contents of the mapped drive of the data stored on the CIFS server (e.g. \\rstore1\sharename$).
2. Right-click the file or folder in the mapped network drive whose Snapshot copies you want to view or manage.
3. Click Properties.
Properties for the file or folder you selected are displayed.
4. Click the Previous Versions tab.
A list of available Snapshot copies of the selected file or folder is displayed in the Folder versions: box. The listed Snapshot copies are identified by the Snapshot copy name prefix and the creation timestamp.
5. In the Folder versions: box, right-click the copy of the file or folder that you want to manage.
6. Perform the appropriate action:
6a. If you want to view data from that Snapshot copy: Click Open.
6b. If you want to create a copy of data from that Snapshot copy: Click Copy.

WARNING: If you click on "Restore", it will replace the contents of the folder or file you've selected with the previous version you've highlighted in the "Previous Versions" tab. You will lose any data that has changed since that snapshot was taken. It is much safer to copy back files you want to recover either the "Copy" button or by opening a snapshot and dragging and dropping the files you want to recover in Windows Explorer.

Data in Snapshot copies is read-only. If you want to make modifications to files and folders listed in the Previous Versions tab, you must save a copy of the files and folders that you want to modify to a writable location and make modifications to the copies.

7. After you finish managing Snapshot data, close the Properties dialog box by clicking OK.
