Which means that if the compression/decompression fails, it may corrupt the entire backup. I don't trust compressed tars for backups.
I think the way to look at that is:
a) if the compression fails, the tar'ing will fail, therefore your backup will fail. b) if the compression fails, you've got other things to worry about than a missing backup.
It can fail silently, so that the user doesn't notice unless he tries a test recover as part of the backup procedure.
That is only a variation of (b) above - if you can't trust your backup procedure, a missing backup not your primary problem.
Or, the backup media can fail (read error) several months later when you need to do a recovery. Even if that error only affects a few bytes, you can loose the entire tar.
It's really just another variation of (b) - the backup media or the physical storage location is not safe/trustworthy. /Per -- Per Jessen, Zürich (11.1°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
