If a file is stored on a network share (H, I, and other network "drives" that may be found under My Computer) this file can be rolled back to a previous version, provided that the file has been through at least one back-up cycle. Backups happen at noon, midnight, 7AM and 7PM daily. Each backup is kept for four weeks.Because of this, in the event of data loss, there's a very good chance that there will be some data to recover. You can use this feature to save individual files, or even whole folders.
1. Navigate to the file or folder in question.
2. Right-click the file, and from the context menu that appears, choose Properties.
3. In the Properties dialog box, choose the Previous Versions tab.
In the center of this tab, a box shows the dates that are available for restoration. Click on the date you would like to restore the file to, then click the OPEN button at the bottom right hand corner of the dialog box. DO NOT HIT RESTORE
4. You will be able to copy/paste the folder out of the back up as normal.
Important Items to Consider
The Previous Versions function is only available on files that are saved to specific network drives. Files that are saved locally (C: drives) cannot use this functionality.Currently, the H: and I: shares are the only network shares that support Previous Versions functionality. Individual departments may have specific network shares assigned to them that may support this functionality as well.
