Standard Backup Retention Policies
These are the standard backup policies for users that have contracted with UF-IT's Tivoli backup group to provide backups of their data on Research Computing systems.
|Number of copies held onto||7 copies will be held onto, unless the following restrictions go into effect|
|How long to keep old versions of a file||60 days from writing new version|
|How long to keep a deleted file||90 days from last backup of file.|
What the Policy Means
- Number of copies held onto simply refers to the number of copies of any single undeleted file that is held in the backup system. If you modify a file, when the incremental backups run that new version of the file is backed up, and the old version of the file is kept in the system as a revision. Up to seven copies of this file will be kept until the oldest revision is dropped off. Old versions of a file can also be dropped out of backups due to the next option:
- How long to keep old versions of a file is how long a file will be kept on the backup system once it has been changed. Only the newest version of the file is kept forever.
- How long to keep a deleted file refers to the last backup of a file that has been deleted. Deleted files are treated a little differently from a changed file on the system as it is no longer visible to the user on the main file system, so extra time is given to the user to recognize that a file is missing and request it from backups.
Requesting a file recovery
If a file needs to be recovered from the Tivoli system, please submit a service request in Research Computing's ticketing system at http://support.rc.ufl.edu
