Email is kept for only two weeks, while all other files are maintained for 1 year before the tapes are overwritten. Whenever possible, files should be duplicated on a separate filesystem at regular intervals. Projects which maintain large datasets should purchase equipment and media to provide for their own backups. IR is available for consultation on these matters. The basic schedule is 1 full backup every other week with incremental backups in between.
Backups have a substantial impact on the campus network and are therefore scheduled at night.
Networker maintains an online index of each client. This begins a session between the client and server, and the appropriate online index is activated. Any difficulties with this system should be reported through the x2911 assist system.
