Hi everyone, I installed BackupPC to try it out for backing up Linux systems, and I have a few questions about it.
First, the on-disk compression format makes me nervous. It appears to use the deflate algorithm, but cannot be unpacked with either gzip or unzip. It would seem that the few bytes that adding a gzip header means would be well worth it, since it would buy the ability to extract it without using specialized tools. It also makes me nervous because it isn't a completely off-the-shelf implementation, and doesn't appear to store a CRC in the file; is there integrity checking anywhere? Secondly, I would love to be able to use bzip2 for the on-disk compression of each backup. It appears that bzip2 can be used for archives, but not the regular backups. Is this in the works anywhere? Third, I'm wondering how well BackupPC deals with sparse files. I notice that the examples for tar are not giving -S to detect sparse files. Does BackupPC store sparse files efficiently, even if not using compression? On restoration, what will it do with sparse files -- will it re-create the holes?
