Hi all,
As some of my remote users haven't been to the office for months no
backups of their laptops have been taken.
The reason is VPN is configured one way. Remote users can access
internal resources but no internal systems are aware of their
hostnames. All IPs assigned to VPN tunnels are dynamic and short
lived. It's also harder to have the laptops connected and subjecting
to backup at strictly scheduled times.
My question: is it possible for Bacula clients to initialize backup on
demand rather than running a schedule on the server? They don't have
to be daily. One weekly one executed at convenient time would be much
better than no backup at all.
You can upgrade to a new version of Bacula (on both server and clients)
that has client-initiated backup capability. By default, bacula-dir
makes a connection to bacula-fd to initiate a backup, but it is also
possible to have bacula-fd connect to bacula-dir to request initiation.
In either case, bacula-fd connects to bacula-sd for the actual backup
operation.
Also, keep in mind that the version of bacula-dir and bacula-sd must
always be >= the version of any bacula-fd client in use. Bacula-dir and
bacula-sd are backward-compatible, but bacula-fd is not.
I have seen this situation with remote users worsen due to the pandemic.
I (mostly) worked around this issue by having users access a file server
over VPN along with a owncloud server, rather than the remote users
storing data locally. Their laptops are essentially thin clients, so
backing them up is not that critical.
I'm after a secure solution - just allow clients to perform a single
operation rather than grant root access to Bacula server.
Well, bacula-fd must have read permissions to anything needing to be
backed up. It can run as non-root but will be limited to the set of
files and directories for which it has read permissions.
I'm running an old Bacula version 5.2.6.
Please advise.
Regards,
Adam
