She falls back to so called degraded mode backups dumping to the holdingdisk. You also have specified reserve 100 (that's the default if you didn't change it), meaning that in degraded mode, 100% of the holdingdisk is reserved for incremental backups. But the only disklistentry was a new one, and amanda cannot make an incremental backup when there is no full backup to base it on. Then she gives up. Solution: while testing, you can amrmtape the testing tape, or you need to give more tapes (until you have tapecycle number of tapes).

This seems to be produced by amanda 2.4.3. Not sure of the cause, but just that part in the amstatus code (among others) got updated in 2.4.4. The most recent stable version is 2.4.4p3. I guess upgrading will at least gid rid of that error message. ... localhost:/home 0 17720729k dumping 0k (16:49:27) (reformatted the above line, and added a space) So this seems to be a 17 Gbyte partition. And it seems to be dumping directly to tape, bypassing the holdingdisk. Am I correct? It seems to be taking ages to complete this backup...is something wrong? I don't know. How long is it running? How long would it take to write 17 Gbyte to tape at full speed? Maybe your tapedrive is not streaming anymore, because the bypassing of the holdingdisk? If the datastream cannot follow the speed of the tapedrive, the drive has to stop/backup a little/restart and this has tremendous influence on the throughput (not to mention the wear and tear on the drive and the cartridge!!!). If this is indeed the case, possible solutions are: - use a larger holdingdisk - divide /home in smaller chunks, each fitting into the holdingdisk (best is fitting at least two of them: one taping and rest dumping) See docs/disklist in the sources for an example how to do this. - disable software compression if cpu is the bottleneck (amstatus in amanda 2.4.4p3 also has better indications of dumps that bypass holdingdisk.

When it is done, what speed is reported in the email the dump sends you? By that, I mean does it match within say 10% of the drives rated speed of data transfer? Also, note the holding disk area of only 296,960k, (297 megs) which is not nearly enough for amdump to stuff a 17,720,729k (18Gb? break that into subdirs and use tar, not dump if thats what you are now using) dump, and this is forceing amdump to write directly to the tape, possibly with lots of under-runs that will result in the drive stopping, backing up and restarting (shoe shining) which takes time out of the write time, so I'd expect the write speeds reported to be a bit slow. So in addition to giving the machine a unique name that can at least be resolved in the /etc/hosts file, find it some more holding disk area. The localhost issue probably won't effect the backups, but it sure will mung any chances of a clean recovery should you need it. Max. Max Waterman wrote: Thanks everyone for helping.
