I agree on that, but I have never experienced the problem myself, just read about it one or two times over the last years. At the time, I wasn't familiar with the attrib file contents. Now, it makes sense that this problem could occur. But I might be mistaking things. The important part is that if you run into problems when restoring after changing the XferMethod, changing it back for the restore might help. > Second, how do tar incrementals signal deleted files if they don't use > the "deleted file type" (10) attribute? They don't. tar can't detect deleted files. Deleting a file doesn't change its modification time, it deletes it ;-). > I have never used tar as a XferMethod before so I don't understand how it > works differently from rsync here... Well, you don't have fileLists ... a full tar backup is just a tar stream of all the files on the sender side, which is then interpreted by BackupPC and integrated into the pool. An incremental tar backup is a tar stream of all the files on the sender side that have changed since a timestamp. Files not present are either unchanged or deleted (or moved to a new location). There's no way to tell which. Regards, Holger ------------------------------------------------------------------------------ Come build with us!
