I personally dislike compressed tars for backups. A single byte error in the media, and you can not decompress it. The entire tar archive is lost. Very unreliable.
In my case, the issue is moot, but I never lost an archive due to the issues you've raised here. There's not only faulty / degraded media to worry about, but there are varying calibrations / alignments across optical drives. The potential for catastrophic loss definitely exists. In fact, I actually think this is why I stopped using CD/DVD media for backups. I switched to running all my backups to redundant external hard drives. This method means at all times I have at least three copies of everything critical ... the 'live' filesystem originals plus two physically separate 'mirrors' (rsync.) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
