Also, there's a bug in current versions of gnu tar that cause it to produce extremely large estimates if the filesystem contains sparse files. On Fedora Core x86_64 machines, attempting to back up /var can be a challenge because tar thinks /var/log/lastlog is a terabyte or two in size and produces estimates that are somewhat larger than my 50G tape. See the commentery in https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=154882 The usual symptom of this bug is Amanda refusing to dump the DLE at all, but I can imagine it forcing a dump to go direct-to-tape instead of to the holding disk under some circumstances. > I noticed that the example amanda.conf file has specified "use 290 m" > for the holdingdisk section. > Many people seem to forget to adapt that arbitrary number there. Maybe we should change it to "use 1t"? That'll get people to notice it, won't it? :-) -- JF
