They're not. Amanda has the concept of a "holding disk", where it spools your backups before writing them to tape. You can instead have it write them directly to CDRW-Taper, which needs its own place to store stuff until it has enough to write a CD. That place is $DUMP_DIR. > Overview.html says > "The idea is to have the taper copy the backed up data to several > intermediate directories, each representing a single CDRW.

The rest have to be stored on the disk until a human (or trained monkey) can physically change CDs and burn some more. There is supposedly some support for disk changers, just incase you have one, but I don't think it's tested. > All this leaves me thoroughly confused about whether I need to have > disk space sufficient to hold my entire backup at once or not.

I have successfully had CDRW-Taper automatically burning the first disc of a backup run, but I wouldn't call it well tested. I had to fix a few bugs to make it work and I may not have gotten them all. > The authors of this package might want to look at, or even use, > cdbackup, which has multi-volume capability. The (upstream) authors of this package don't seem to care about it anymore. I'm personally using bacula these days, not CDRW-Taper, and I'm looking for someone to take over the package. I can sponsor uploads. > P.S. I'd think amanda-cdrw-taper would be a better name for this > package. This is possibly true, but probably not worth the trouble of changing it. -- Sam "Eddie" Couter | mailto:[EMAIL PROTECTED] Debian Developer | mailto:[EMAIL PROTECTED] | jabber:[EMAIL PROTECTED] OpenPGP fingerprint: A46B 9BB5 3148 7BEA 1F05 5BD5 8530 03AE DE89 C75C
