Backups


 

The Helix systems are backed up regularly by the Operations staff. Full backups of home directories are done weekly, and incremental backups are done daily. These tapes are kept onsite for four weeks. Every four weeks a special full backup of home directories is done and sent offsite; these tapes are kept for eight weeks.

E-mail backups are done at night; e-mail messages that are lost the same day that they were created would not have been backed up yet and therefore can not be restored. Snapshots (software backups) are done every six hours on home directories; therefore even files that were lost on the same day that they were created can most often be restored.

If you need to have files restored, send e-mail to the operators at the address operators@helix.nih.gov.
