<p dir="ltr">Excuse me while I snicker about the "big boys" "dedupe copy". :-) </p>
<p dir="ltr">No. Bacula doesn't have a dedupe process. Vaulting, IMHO, is nothing more than an intermediate copy - I've seen it used as a spinning rust hot backup with great success. Bacula can create that and later archive to slower media - tape, optical, MO, no paper (yet).</p>
<p dir="ltr">I think of dedupe at the block level. For my uses, the RAM cost is far higher than a cron job that scours user write space for copies of large, archived input data sets instead of links.</p>

data center then replicate that in the background to another unit at an offsite location. Even if you use tapes for offsite you can backup everything to the dedupe units first then copy to tape from there. In NetBackup they call that duplication from one
storage unit to another, Vaulting. One of my original questions in this thread was asking if Bacula or other OSS solution had something like this Vaulting.<u></u><u></u></span></p>

<p>My backup rig is in the same rack with the machines it backs up. Politics and network limitations prevent relocating it elsewhere. So a monthly extraction of full backup tapes to my office across campus is my solution. I use a specific set of LTO6 tapes
just for fulls with a rolling set for incr and diffs.<u></u><u></u></p>

<p class="MsoNormal">I have bacula setup on ~10 clients with daily incremental, weekly differential, and monthly full backups implemented. Bacula works great and any individual file or subdirectory can be restored on demand if needed. Anytime I've had to
restore something, it just works. Once I got the main configuration template for one client working then the rest of the clients were pretty straightforward. So, I know backups and restores work. The problem we haven't dealt with yet and have plans to rectify
is that the backup server is still in the same building as the clients being backed up...<u></u><u></u></p>
