Hello.
* Does the Windows client of Bacula implement CBT based on VSS or does
it simply iterate files in the created snapshot? Does it transfer
changes within files only at all or always the whole changed files?
Even without CBT it could apply some RSYNC-like approach.
AFAIK it works on files and transfers them as a whole.
This might be a drawback in some cases, where you have a huge file which
changes only a little everyday (Outlook's .pst files anyone?).
* Can the Windows agent be configured remotely
No, but see below...
e.g. to change when to backup, which files etc.?
You don't set these in the client (what you call the "agent").
You set them in Director's conf (in other words on the server).
* Can the agent be updated automatically when a new version of Bacula is
deployed? I've only read about some installers yet and stuff about
compatible versions.
Not by itself (of course you can have other deployment tool in place,
like you would with any other software).
Notice, however, that the client rarely *need* to be upgraded: unless
you encounter bugs or need new features it's typical for old (even very
old) clients to work with new server versions.
* Does Bacula support some sort of tenants?
I don't know what you mean with "tenant", sorry.
For ABB I'm using one BTRFS
subvolume per Windows client to strictly seperate data. While it makes
deduplication less efficient, that wasn't too much of a problem yet.
Looking at the architecture with centralied database and storage pool,
it doesn't seem supported/possible to me currently?
You'll have a single database (unless you do multiple different
installation, which I don't see any reason to do).
You can still have as many pools as you want (in fact I often have a
different set of pools for each client) and/or multiple storages
(different directories, ZFS pools, etc...).
* What's the preferred tunneling for Bacula, OpenVPN or SSH? I'm using
ABB with OpenVPN and it works pretty well. But maybe the Windows agent
has some hooks ore something where SSH-tunnels might be created and
those used instead?
AFAIK there's nothing SSH related.
OpenVPN will do (as any other tunneling solution, I guess).
