1. Amanda Mitch Collinsworth Cornell Center for Materials Research

2. Intro zClient/Server style backup system zFree, open source zRuns on most unix

3. Intro... zA backup manager, not a backup program zClients run own native backup programs e.g. dump or GNU tar zCan backup Windows via Samba using GNU tar

4. Features: standard tools zTapes written using standard software zCan restore without any special software using standard tools: mt, dd, gzip

5. Features: efficiency zDumps to holding disk first, allowing multiple dumps in parallel zDumps then copied from holding disk to tape, allowing streaming tapes to keep streaming

6. Features: Planner zNot locked into a specific schedule zPlanner phase collects estimates and determines what dump levels to run zIf a client is down or hung, note in report and keep going

7. Features: tape balancing zBalances full dumps throughout dump cycle zBackup runs for about same time each day

8. Features: tape changers zChangers supported via external interface zEasy to add support for a new device

9. Features: compression zClient or server zServer: software (gzip) or tape hardware

10. Features: scales well zEasy to add filesystems to backup list zEasy to add tapes to the tape cycle zEasy interactive restores from any client

11. Features: fails gracefully zTape errors don’t stop the show zDumps continue to holding disk zFlush dumps to tape after correcting the error

12. Amanda: deficiencies zWindows support (smbtar) currently a kludge zNo MacOS support prior to OS X zMultiple tape in a run ok, but one dump image can’t span tapes
