Backup Central

Hi,

I'm looking for a backup solution which will provide backups to all users,
in the form of a .snapshot directory with periodic kept backups.

I've seen systems at universities, other places of work etc, which provide a
'.snapshot' directory as a subdirectory in all user home dirs. The
rsnapshot utility seems to only create a backup in one place, which users
would have to navigate to themselves.

In reality, for the system to allow users to retrieve backups themselves,
they need to easily find the backups. Is there a way of doing this? I'm
guessing that all that would be needed would be to symlink from
/home/{user}/.snapshot folder /backups/snapshots/{user}

Any way to automate this - as part of the rsnapshot tool?

Dave

You could probably just run a shell script like this every night:

------------------------------------------------------------------
#! /bin/sh
home=/home
snapshot_home=/backups/snapshots/daily.0/server$home
cd $snapshot_home
for user in *
do
# If a symlink /home/user/.snapshot does not already exist, then
# create a symlink to /backups/snapshots/daily.0/server/home/user
if [ -d $user -a -d $home/$user \
-a ! -L $home/$user/.snapshot ]; then
ln -s $snapshot_home/$user $home/$user/.snapshot
fi
done
------------------------------------------------------------------

You don't need to run it at the same time as rsnapshot.
In fact, you might want to run it whenever you create a new user.

You should chmod it so only the user can read it:

chmod 700 for dirs, and 600 for files.

There should be no need to chmod the symlink. The directory
/backups/snapshots/daily.0/home/{user} would have the same
permissions as /home/{user}.

But that does remind me that its a good idea to read section 7.2
(Restoring backups - All users) of the rsnapshot HOWTO, here:
http://www.rsnapshot.org/howto/1.2/rsnapshot-HOWTO.en.html#all_users
which explains how to make your snapshot directories read-only
for regular users to restore from. You wouldn't want regular
users to be able to change the files already backed up...
