UMIACS conducts backups to provide accidental deletion coverage. We aim to provide 90 days of coverage, at one backup per night. However, this coverage may not be perfect, as our backups are very coarse. Depending on the size of the change and size of the file, backups may be periodically missed. Furthermore, files that change often may not have all versions backed up to 90 days, and files which were created very recently may not be backed up.
Volumes that are Regularly Backed Up
Windows hosts at UMIACS store user directories on their local drives. Supported, UMIACS-managed hosts are automatically backed up using the Institute's backup system. It is important that your machine remains powered on at all times so that these backups are able to complete daily.
Volumes that are not Regularly Backed Up
By default nodes are not backed up. If you need a node backed up, please submit a ticket to get in contact with staff. The directories typically included in the backup of a node are /export and /etc.
Laptops and non-standard hosts are not automatically backed up and should be manually backed up by their users. Druva is a common solution used by many within UMIACS for backing up laptops.
