You're doing it wrong. ;-) You're not really doing it ''wrong'', it just depends on what your needs are. One drawback to using just rsync is, if a user deletes a file, then needs it back after the rsync was run again, the file may no longer be in your backups (similar if the user modified it and needs the original pre-mod file back). If you're okay with that, then rsync is fine for your needs. rsnapshot uses rsync with hard links to be able to efficiently keep snapshots (not point-in-time snapshots, just whatever was present when rsync sync'd each file) on a periodic basis. bacula is a more sophisticated method for doing this efficiently across multiple hosts. LVM snapshots allow for a real point-in-time snapshot (which can then be backed up with your favorite tool). > I may be doing it wrong but it always works. It always works until it doesn't. This is unfortunately all too true when it comes to backups. It's easier to inspect backups on disk than when they used to be done to tape, but it's still good to verify them outside of your normal backup routine periodically. --keith -- kkel...@wombat.san-francisco.ca.us ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] [SOLVED] Re: Backup Suggestion on C7
I'm sure some people will tell me I'm doing it wrong but I always just use rsync for backups, automated in cron. I may be doing it wrong but it always works.

Hi list, I'm building a backup server for 3 hosts (1 workstation, 2 server). I will use bacula to perform backups.

With one single machine and the current state I can't use multiple storage daemons. There are other ways to store host volumes on different devices? My second solution was, use only one storage daemon (on the same host) with a single device LVM over mdraid, create pool for each hosts and limit the size for each volumes on related pool.
