backup ibay containing many hard links
« on: December 11, 2013, 04:51:03 PM »
Dear SME Fellow's

I have a question regarding sme backup.

in one of my Ibays I am running a version control system witch uses rsync internal in the ibay.

I would like to know if all hard links will be copies in the backup set? If yes the backup will grow extremely fast.

There are potentially lots (and lots) of factors that could affect your particular situation: specific backup procedures, specific backup destination, specific backup configuration settings.

The best way to find out would be to do a backup and see what you end up with.

I might explained my self wrong.

the rsync is setup and uses hard links witch works just fine.

The question is how SME backup (DAR) handles Hard links.

Already read the first link yesterday :-)

I just can't see an answer to my question. Maybe because of my poor English.

My reading of the references says dar handles the hard link correctly, ie no copies..so your worries with the size of the backup growinmg rapidly can be ignored
