 Posted: Wed Sep 05, 2007 7:48 am Post subject: network backups with rsync, keep deleted files? |
 |
|
I'm going to use rsync to make regular syncs of a drive in my workstation to my server, so obviously the two drives will be kept identical just in case.
I've got that setup and working well, but I'd like to be able to have rsync automatically copy any files that are to be deleted from the backup to another folder on another drive (because I deleted/renamed/whatever them from my workstation). I've checked out the manpage, and a few options stuck out at me:
| Code: |
-b, --backup
With this option, preexisting destination files are renamed as each file is trans-
ferred or deleted. You can control where the backup file goes and what (if any)
suffix gets appended using the --backup-dir and --suffix options.
Note that if you don't specify --backup-dir, (1) the --omit-dir-times option will
be implied, and (2) if --delete is also in effect (without --delete-excluded),
rsync will add a "protect" filter-rule for the backup suffix to the end of all
your existing excludes (e.g. -f "P *~"). This will prevent previously backed-up
files from being deleted. Note that if you are supplying your own filter rules,
you may need to manually insert your own exclude/protect rule somewhere higher up
in the list so that it has a high enough priority to be effective (e.g., if your
rules specify a trailing inclusion/exclusion of '*', the auto-added rule would
never be reached).
--backup-dir=DIR
In combination with the --backup option, this tells rsync to store all backups in
the specified directory on the receiving side. This can be used for incremental
backups. You can additionally specify a backup suffix using the --suffix option
(otherwise the files backed up in the specified directory will keep their original
filenames).
|
I hoped this option was what I wanted and tried to use it by setting the -b flag then using '--backup-dir=/home/telexen/deleted-backups', but it didn't seem to do anything at all. Am I using it wrong or did I just interpret the description wrong? Is there another option that will allow me to do this?
*edit*
I just realized this got put in Unsupported Software...I meant to put it in Other Things Gentoo. Maybe a mod could move it for me if it seems out of place? |

Heh...I guess I wasn't using --delete when I was testing the functionality of --backup and --backup-dir=...
Works fine when I use --delete.
Oh well. |

Hi Telexen,
I never realised Rsync could do that. I rsync between my Mac laptop and my Gentoo box with a nightly cron job. I use a non delete script , and another manually run script with delete. Obviously I end up with duplicates, but I'd hate to lose files as i do use both boxes regularly. This would be a very useful modification!!
Nice one.
Cheers
Ferg
