Re: [Bacula-users] restoring old data

Thanks Bruno it helped me quite a lot.

For the record, I used new windows version of bacula which now includes bls and bextract programs, which I used.

So far i have tried over the network and it successfully restores many files before it fails (i think it is network problem because I couldn't copy the whole volume file in windows either...). I'll try to move the files locally on a usb drive to try and see.

Thanx a lot... I was afraid I would have to setup whole network of computers to do this, or worse:)

I have one old filevolume containing data i whish to restore. Metadata in the sqlite database concerning this filevolume, seems to be purged, so i tried to restore it by using bscan.... which gives me an error and no metadata seems to be restored to the catalog:

I Damir, bls (list content) and brestore would be your friends in this case.
You don't need any db to work with.

See documentation in the bacula.org website.

I think you could even use them from a recent version on a another server.
The data should be restored to a windows client if you don't have specified the "compatibility" flag.

Hope this help you a bit
