Hi All,
I've recently implemented Bacula as the storage agent for 14 Debian
Sarge servers writing to disk and 1 server writing to tape. Great. What
I now need to do is use Bacula to create a DVD image for me. Ideally
what I'm looking for is the option or ability to use Bacula as the
transfer medium. I have the bacula-fd installed on the client server and
want to pull across to the bacula-sd the various files/directories I
want. Once there I want to write those files to DVD. BUT, I don't want
to write them as the bacula volume format but as the standard file
format they exist in.
This would require you to restore to a location on the machine with the
dvd writer, and building the DVD images from there.
But there are other problems: You would need a quite sophisticated
program to decide which files to put on which disk once you have more
data than can be put on a single disk. That's one of the reasons for
tar, for example, but Bacula can also handle such things :-)
The idea being that in the event of a serious
fault you simply want to insert the DVD into a machine somewhere and
then copy the files to the appropriate locations.
Apart from the effort to create the DVDs, you would also have to manage
the volumes manually, i.e. finding the disks you need for recovery.
Sadly I'm at a loss as to how to do this. I've looked at the Pool
options and it states;
Backup
*Archive
*Cloned
*Migration
*Copy
*Save
With no reference to what the "*" means nor any details about what these
other modes mean. I was hoping that the 'Save' option means that the
data is quite clearly saved to the destination indicated by the
bacula-sd but can't find any info either way.
Bacula only supports its own volume format, and it's unlikely anything
else will be implemented in the near future.
The "*" means unsupported, by the way, and I think in many cases
unsupported also means "not yet defined what this really is".
I know I could do this by simply tarring up the correct directories and
then writing them to disk but then I lose all the options that bacula
gives me.
Correct, but the options Bacula offers can only be used with Baculas
native volume format.
Any help at this point would be appreciated.
Sorry, no real help, but I don't think you overlooked anything that
could help you here.
Perhaps using rsync is a better option for backups for you.
By the way: DVD backups are currently difficult i my opinion.
