No. It does it better. There's a FAQ on this too. --On November 14, 2008 2:02:20 PM + Prashant Ramhit [EMAIL PROTECTED] wrote: Hi All, How is it possible to configure amanda for the following set up Full backup on Saturdays and Incremental on Monday till Friday.

Since tar doesn't really have the same concept of levels, Amanda fakes it by writing similar information in /etc/amandates. Neither one has any idea of multiple configs, so the same file will get updated each time you run any of your configs. So when your 'weekly full' runs it will update the file, and then when your 'daily' runs, it will be expecting to back up files newer than the last 'daily' run, but dump or tar look for files newer than the times in the dumpdates/amandate file and will only be backing up files newer than the time of the 'weekly' run. The end result is that your daily set of tape may be unable to restore the entire filesystem. Your weekly set should be OK since its always a full. Frank that y Excellent explanation Frank, thanks, I needed that. But this also points out that the fix would appear to be fairly simple, just a matter of moving the location of this dumpdates/amandates file to where ever that keyword points to in the individual amanda.conf. Or is this something thats carved into whatever stone dump/tar is cut from, and not an amanda function? The latter case, amandates, certainly seems to indicate its an actual amanda function and therefore subject to being whatever the coders want it to be including its location. I don't think amandates' location is configurable (unless its been added into the beta releases). It would be a nice feature to have though. Of course, dumpdates' location is set in stone in most dump programs. I guess you could compile your own, but it would still be the same for all configs unless you built multiple amandas each configured with a seperate dump executable. I think it would be nice if Amanda was friendlier to multiple configs so the run times could overlap as well, but I would suspect that would also be quite a bit of work.
