Windows Backups

  • You must ensure that all restores finish before the next  backup starts (at midnight).
  • It's advisable to consult IT Staff if you are restoring a large directory structure.
  • The backup servers are normally powered down to save energy.

Every filesystem has a corresponding mirror copy on a backup server. The mirror copy contains the filesystem as it was at around the previous midnight, along with incremental changes. You have to know the name of the server to access the backups. We provide a web interface which lists all the filesystems - you can click on a filesystem to get the name of the backup server and see its current power status - the interface will also wakeup the backup server for you.

When you've found the name of the backup server you require, and the server has been woken up, you can access the backups by running ...

Explorer -> Tools -> Map Network Drive

In the Folder section of the popup window, enter


The server window which appears will have all the backup filesystems on that server - select the filesystem folder you require, and use normal copy commands to restore files or folders.

Accessing Increments

The backup system saves all files which have changed over the last 30 days (for some filesystems this is 7 days). These backups are saved in the daily_changes subdirectory of the backup. For example, to restore a file which changed on the 20th of the month, look in the daily_changes/20 folder.

Note that increments are compressed to save space - so have to be uncompressed.
