-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all. A while ago I asked some questions about doing incremental backups with tar. I have done my initial backup using the g flag, and that went just fine, giving me the list file, along with the 2 gb archive that I was expecting. However, when I did the same thing the next day, the resulting tar file was only about 765 K in size. My idea of an incremental backup was that tar would keep the original archive, and delete in that archive only the stuff that wasn't on the hd anymore, and add stuff to the archive that is on the hd now, but that wasn't there when the archive was created. Obviously, as I found out, the g flag doesn't modify the behavior of the c flag, like I was assuming that it would. What I'm trying to achieve here is to have a full tar archive. Upon subsequent backups, I would like for tar to delete in the archive whatever doesn't exist in the backup source directories anymore, and for tar to add to the archive any new files that are in the source backup directories, but that weren't in the archive before. I'd also like for tar to update files in the archive that are still in the backup source directories, but that have been modified since the last backup. Looking at the tar man page, I see the --delete flag, and the --update flag which should do what I want, but I'm not sure if I can use these together. If someone knows how to get tar to do what I'm looking for, could you please post a sample command line for tar, which backs up dir1/ dir2/ dir3/ into backup.tar? I've been doing these backups before, but I always had tar create a whole new archive every time, and it would of course be better if tar could only update what has changed between the source backup directories and the archive, rather then creating a new archive every time. I hope that what I'm looking for makes sense, and thanks in advance for any ideas.
