(assuming that filesystem is supported by the terastation) and do i simply just mount the terasation to /var/lib/backuppc/ Yes you can mount it as /var/lib/backuppc i guess you are limited to what network filesystems it supports. if it support SAN style mounts i would go for that. iscsi or similar. if it only support filesystems, go for a a cluster filesystem. and if it only suport smb and nfs you are left with only nfs as the possible choise. now nfs works just fine, but it does not scale very well. so you might have to experiment with how many backups you can simultanusly run at a given time. kind regards Ronny Aasen - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.

AFS doesn't really fit since you'd need to create one large BackupPC volume, so you're just moving the problem from local to remote server (that is managing a very large chunk of file system).

BackupPC doesn't provide a mechanism to have fine-grained
per-user permissions when browsing backups. The host file
users have permissions for the entire host: browsing, editing
the configuration, starting and canceling backups, etc.
Enforcing permissions is a bit difficult since apache doesn't
provide the uid and gid - just the username - and the backups
just contain the client uid/gid. There is no guarantee that
user names and uid/gids are common between the server and
client.
that's not a guarantee, but when you have ldap/sql/nis user-uid
mapping it's quite commonly so.
I assume one could deny access if the user didn't map to a uid.
mapping a user to the wrong uid would be hard to detect. But it's not
your stock configuration anyway so some prerequisites like common user
database can be expected.
Perhaps we could have a new config variable which forces the
browse path for non-admin users, eg:
$Conf{CgiUserBrowseChroot} = {
'user1' = '/home:/user1',
'user2' = '/home:/user2',
};
(/home is the share, and /user1 is the path relative to
that share)
There could also be a wildcard form that allows any user to
browse their folder:
$Conf{CgiUserBrowseChroot} = {
'*' = '/home:/*',
};
One drawback is this host won't appear in the pulldown in
the navigation bar, since that is based on the hosts file.
So the user has to navigate to their host by knowing the
correct URL.
So there is no way to do this currently. Having 1000 hostlines is not
that big a problem for the user. Since it's the admin that have to live
with a _Lng_ dropdown box.
would backuppc deal with a hostsfile of ~1000 lines and 1000 files
saying server-user[].pl

Hello. I have installed backuppc + apache2 ldap_auth on debian etch and it's working great. Now i have one challenge that i have not been able to find a solution for in the docs or mailinglist archives. If it's been answered allready I would very much like a url. I am taking backup of a directory /home, containing ~1000 users. And i want to allow each of the users access to restore his own files. But NOT to read/restore files that he normaly would not. Example: user1 have a file in /home/user1/private.txt that have 600 permissions.
