Full Discussion: Rsync for back up, external HD
Operating Systems OS X (Apple) Rsync for back up, external HD Post 302824629 by drl on Friday 21st of June 2013 08:17:57 AM

Hi.

For backup of files, I use rsnapshot, possibly in your repositories, more information at rsnapshot . It uses rsync as part of a larger organization process. I have used it for more than a year, it allows recovery of individual files, and uses hard-links to create a very compact backup, yet still "addressable" by date-time of collection. You can set up cron jobs to do hourly, daily, weekly, monthly backups from the remote gathering computer. I backup at 4-hour intervals.

For a very quick backup of everything, I often used a tar.gz file -- it quickly restores my files to updated, and newly installed systems with no trouble (although you may not want every old file).

For cloning to create a bootable image, I suggest you look at Clonezilla - About -- it will use dd as a last resort, but will first check to see if it can copy by omitting unused sectors. (I use software RAID, which causes a dd copy.)

Always experiment before you commit important data.

Best wishes ... cheers, drl

rdiff-backup-fs

RDIFF-BACKUP-FS(1)					      General Commands Manual						RDIFF-BACKUP-FS(1)

NAME

       rdiff-backup-fs - Filesystem for accessing rdiff-backup archives.

SYNOPSIS

       rdiff-backup-fs <mount_point> <repository> [repositories ...] [-option ...]

DESCRIPTION

       rdiff-backup-fs is a filesystem in userspace that reads rdiff-backup archives and provides convenient access.

OPTIONS

       --debug <0-4>
	      Run rdiff-backup-fs in foreground with given verbosity of debug messages.

       -f, --full
	      Store information about all revisions in memory. CAUTION: this may take a lot of memory if your archive contains many revisions.

       -l, --last
	      Displays	files from the most recent increment as directories, each holding every version of the file. CAUTION: this stores informa-
	      tion about all revisions in memory and therefore may take a lot of memory if archive contains many revisions.

       -c <n>, --caching <n>
	      How many files retrieved from the rdiff-backup archive may be cached by filesystem. By default rdiff-backup-fs will cache up  to	10
	      files. If this switch is set to 0, no caching will be done.

       -r <n>, --revisions <n>
	      How many revisions should be stored in memory for on demand revision retrieval. By default rdiff-backup-fs will store up to 10 revi-
	      sions in memory.

       -d, --directory <path>
	      Set directory for directory with temporary files. By default rdiff-backup-fs uses /tmp.

       -v, --version
	      Print version of rdiff-backup-fs and exit.
