Actually, IMO, an rsync job is safer than raid, it covers more failure modes, but not as fast.
It depends on how you define "safe". In my book, the longer a system runs without two identical copies, the less safe it is. There is no way an rsync copy will ever catch up with a RAID1 mirror.
problem with raid is that nothing verify disk failures on unused data. the raid purpose is uninterrupted running, not data saving.
Depends... you can have a background task run and read through the entire disk. If anything comes up as different between the two copies, you'd know -- at least that's what my lsi card does about once a week.... However, if you only had 1 disk, that won't protect you against bad software or malware. I'd setup the 2nd disk as a backup disk. Use a tower of Hannoi rotation and use backup levels. That way if your disk gets thrashed by SW, you can restore from backup as soon as you get HW to drop-in, But if you partly format a partition or overwrite stuff - a RAID1 will help preserve the damage! -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
