Hi All, I am writing a backup program for my computer. brief outline is as follows.
Running ubuntu 10.04 2 main partitions, / and /home, both ext3. 1 external usb hdd, ext3, mounted to /backups/main. once every couple of days, rsync backs up, using following command, everything worth backing up in / and /home partitions to a folder /backups/main/Full. command: "rsync -vrhRupElog --delete-during --delete-excluded --exclude-from=/backups/.config/full.exclude --log-file=/backups/.logs/full.rlog / /backups/main/Full/". this works perfectly now what i want to do, is every few hours, rsync ONLY the files changed in the last few days to a folder in /backups/main/Incremental/YYYYMMddTHHmm, where the yyyy... is a string representing the date and time. (and then tar.gz the previous directory to save space) the command i am using for this is : "rsync -vrhRupElog --delete-during --delete-excluded --exclude-from=/backups/.config/incremental.exclude --log-file=/backups/.logs/incremental.rlog --compare-dest=/backups/main/Full/ / /backups/main/Incremental/Full/20100716T1355" the incremental.exclude differs from the full.exclude only in that i also exclude .mp3, .avi and other large and non-critical file types. the problem is that rsync is behaving as though it is ignoring the compare-dest option. it throws no error about this dir not existing, and i have tried giving it as a relative dir to the destination with same result. interestingly, i tried to see if something was wrong with my statments by doing: mkdir ~/rsynctest/dir1 mkdir ~/rsynctest/dir2 mkdir ~/rsynctest/dir3 nano ~/rsynctest/dir1/file1 (wrote the line hello world and saved) nano ~/rsynctest/dir1/file2 (wrote the line hello and saved) cp ~/rsynctest/dir1/file* ~/rsynctest/dir2/ checked md5sums of both files in both dirs to ensure they were identical the did rsync -rvu --compare-dest=/home/kevin/rsynctest/dir2/ /home/kevin/rsynctest/dir1/ /home/kevin/rsynctest/dir3/ the two files from dir1 were copied to dir3, even though identical copies, with the same names, existed in dir2. i also tried this again with the compare dir relative to the dest dir, i.e.: rsync -rvu --compare-dest=../dir2/ /home/kevin/rsynctest/dir1/ /home/kevin/rsynctest/dir3/ again with same result is this a bug, or have i got the wrong end of the stick regarding --compare-dir? thanks all.
