I would check the speed as FUSE file systems can tend to be slow... especially since you said your machine is slow. > > The only problem I can think of is that every time backuppc has to do > some reading the FUSE will also need to decompress images on the fly.

Decompressing only occurs if you need to read the underlying file as otherwise the md5sum (and/or other file stats like timestamp, size, owner, perms) are used to check for changes. Plus, the same decompressing occurs if you use the built-in zlib compression. > > > _______________________________________________ > BackupPC-users mailing list > BackupPC-users@lists.sourceforge.net > List: https://lists.sourceforge.net/lists/listinfo/backuppc-users > Wiki: https://github.com/backuppc/backuppc/wiki > Project: https://backuppc.github.io/backuppc/ _______________________________________________ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List: https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki: https://github.com/backuppc/backuppc/wiki Project: https://backuppc.github.io/backuppc/
