Snapshot – Backup of home directories and shared volumes

.snapshot are hidden readable copies of the files in your home directory and on shared volumes. Snapshot can be used to retrieve lost or deleted files.

  • Snapshot cannot be used on Mac, but Mac users can retrieve files from .snapshot via Windows or UNIX computers.
  • Note that .snapshot cannot be used with Vortex. In Vortex you will find deleted files on the Trash tab.

Your home directory is located on a disk in UiO's network, but works similarly to a local disk. When you open your home directory, you will find several folders. These are backed up every night, thus reducing the risk of loosing stored files to a minimum. In addition to this, there is the .snapshot service.

The directories will take a snapshot, or backup, once an hour. This is kept for two days. There is also a snapshot taken at midnight that is kept for a week. You can retrieve these snapshots like this:
