Backup Central

Hi,

I have a setup of a server being backed up regularly over a DSL line to
my server at home.
After quite a bad crash I am in the process of restoring the data. There
are some huge directories which I am now stuck a little. For those who
don't know DSL: Here in Germany it's usually a high download speed, e.g.
6 Mbit/s and a slow upload speed, 300 kbit/s in my case. In addition,
the ip is changed once every day, which results in a disconnect.
Now I want to restore the big directories step by step. For that, I
tried to restore like
rdiff-backup -r 02-02-2010
--exclude /var/customers/web1 /home/backup/var/customers
server::/var/customers
but the directory /var/customers/web1 gets restored anyway. An option of
--exclude /home/backup/var/customers/web1 gives an "invalid path
specification" (or something like that) error.
Also, doing it the other way around, first restoring /var/customers/web1
and then /var/customers does not work as the web1 subdirectory gets
restored again (which is exactly what I'd like to prevent.

Is there any way to exclude certain directories from being restored?

Thanks
Dominik

Hi Dominik

Although it is not an answer to your present predicament, I would say
that rdiff-backup is not advisable over an unstable connection. A better
strategy is to run rdiff-backup locally (preferably to a different
machine) and then use rsync to mirror the rdiff-backup repository to an
offsite machine using rsync with the --link-dest option. I recently
posted on this mailing list an example of how to do this. Problems with
the offsite backup process are minimised and you have a primary and
secondary backup.

--exclude '**var/customers/web1'

it really is that simple, thanks! Although I understand the meaning of
** I am a little confused why that matches and to what exactly it
expands to. But for now I am just happy.

Cheers
Dominik

'**' is a wild card that includes '/' so by doing '**var/customers/web1'
you are really expanding to /home/backup/var/customers/web1 which is
the full path of the directory you wanted to exclude.

yes, I get the wildcard pattern, but why does
--exclude /home/backup/var/customers/web1
not work:
$> rdiff-backup -r 02-02-2010 \
--exclude /home/backup/var/customers/web1 \
/home/backup/var/customers server::/var/customers
Using rdiff-backup version 1.2.8

[...]

Fatal Error: Fatal Error: The file specification
'/home/backup/var/customers/web1'
cannot match any files in the base directory
'/var/customers/'

That's why I would be interested in the actual expansion of ** and how
to write it without wildcards. And yes, it's more out of interest than
of practical usage now

Thanks
Dominik

I really need to read more closely. It completely escaped me that you where
doing a restore. The issue is on the server side. The root for the server
is /var/customers so /home/backup/var/customers/web1 will not match. The '**'
wildcard will create a match with /var/customers/web1 on the server side.
