I also am educational and have an LTO2 setup. My weekly backups are currently about 150GB, so I let them spool on a RAID1 holding disk for a week, then put a tape in and let them autoflush on the 7th day. I have a rotating set of tapes for 20 weeks, and do an archival dump quarterly. You probably just need to adjust your reserve parameter properly in amanda.conf. The default is 100% is reserved for degraded-mode backups. Set it to something smaller to allow fulls to fit. Matt
Thanks for the pointer, I will try this. I assume I turn off autoflush? I'm going to try with a reserve of 25% - I have a 250 Gbyte holding disk.
