Description:

These file backup schedules and restoration policies apply to user files on stored in home directories accessible on shell.uoregon.edu. This includes user email stored on our central servers, uploaded files, and other data you may store in your UO user account on shell.uoregon.edu or sftp.uoregon.edu.

Backup

User directories are periodically copied to backup media. Although Information Services takes reasonable steps to backup user files, users are encouraged to make their own backups of very important data or data that will not be accessed for long periods of time (months or years). The backup schedule is as follows:

  • Hourly Snapshots: Hourly snapshots of all user home directory filesystems are taken on even hours (2 am, 4 am, 6 am, etc.) and retained for approximately 48 hours.
  • Nightly Snapshots: Nightly snapshots of all user home directory filesystems are taken nightly at 12:00 am and retained for approximately 1 month.
  • Weekly Snapshots: Weekly snapshots of all user home directory filesystems are taken at 12:00 am Monday each week and retained for approximately 4 weeks.

Restoration

Although backups of centrally stored data is performed primarily for disaster recovery purposes by Operations, users can request the restoration of files they have accidentally lost that may have been stored in their email or user directory. Files stored in daily, nightly or weekly snapshots can be recovered by users through the snapshot recovery system. For more information on recovering your data from a snapshot please see our documentation or contact the Technology Services Desk at techdesk@uoregon.edu. Make sure your request covers all of the files you need to have restored.

If you have a working knowledge of UNIX, you can try to restore the files yourself. See Snapshot File Restoration.
