rsync question

sigint-ninja · 10-29-2018, 02:34 PM

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.

Code:

rsync -a

will do incremental backups. See man rsync

I also include the --delete option to remove files in the backup that have been deleted in the source.

Check out rsnapshot for a utility to manage rsync backups.

In addition to -a, you might also need -H if you have hardlinks to deal with in your hierarchy of source directories. Again, see "man rsync"

I do not really understand why do you want to avoid --link-dest.

did you check different solutions on the net already? Did you find something interesting?

sigint-ninja, use --compare-dest instead of --link-dest.

pan64, this might be useful if the destination filesystem does not support hardlinks, in which case --link-dest is ignored.

Please do not answer instead of the OP. Probably you are right, but I would like to know the real original reason.

Yes, I too would like to know why the OP needs this, and I do not assume his reason is the same as the one I suggested.
