[rsnapshot-discuss] Moving to a new disk

[Thierry Lavallee]

Hi, my 500GB destination disk is full.
I need to move it to a 3TB disk.
What is the best method to copy my content from a disk to a new one?
will simple cp do the work?
Thanks

What works:

Source=/Path/to/old/backup
Target=/Path/to/new/backup
mkdir -p $Target
rsync -axH ${Source}/. ${Target}


I've just transferred a backup with about 1 TByte from one disk to
another, needed more than 1 day.

And you should stop all "rsnapshot" jobs during that time.

Viele Gruesse!

Of course, if you're using LVM you can also use pvmove
and won't need to stop running rsnapshots either.

If you've got GNU cp then cp -a will preserve hard links.

If you use rsync, then consider using -S as well, to get more efficient
handling of sparse files, or even of files that can be made sparse.
