Rsync for incremental backup

Hello,

I want to have hourly backup of directory using rsync.

Incremental backup should copy only new or modified files only. How this can be achieved with rsync without --link-dest option ?

I have the script but it uses --link-dest option.

Rgds,
Joy

Hi,

Able to achieve with --compare-dest option.

Now if any file get's deleted from source directory how to keep track? Tried -backup and --backup-dir but creating only empty back-up directory without any files in it.

Regs,
Joy

I'm not sure rsync is the best way to do this.

The most literal (and enterprise-friendly) way to do an incremental backup would be, in fact, to use an actual backup program such as Bacula, but that's a fair amount of overhead.

A more lightweight option would be to simply keep the backups as a git archive and run a "git commit -a" against the directory on a cron schedule. This works most efficiently if the files are text or other forms that git can strip down to just the changes instead of having to archive an entire file, but regardless, git can provide you with not only a complete restoration of changed, moved, and deleted files from the previous hour, but of any hour since the archive was first created.

Thank you for the suggestion.

RSYNC is client specific requirement. Between I am able to backup, deleted files using --backup-dir option.
