Small but well designed server

[andrea]

Well I have to reinvent the network of a small factory (say 10 pc's
and one server).

The os will be debian 4.0 on a dell quad xeon (PE2900) but I have some
doubts.
I don't have much data to store, so I think a raid 1 with the 73Gb SAS
drives would be fine, and maybe add another couple of hot-swappable
big sata disks.

I will use postfix+spamassassin+samba at the beginning and them I'll
move there the web and mail server.

I want to use ldap (which I'm still studying) to centralize
everything.

The questions are these, which file systems / partitioning scheme? I
have a little experience with lvm (used even on a laptop) and think it
would be fine.
What backup system? They tried to sell me a dat system (about 450€),
would't an external disk be fine?

Any good tutorials on ldap and the integration between other services?

I also want to get a shared address book, can I do it easily with
ldap?
And for the users quotas, is it supported only on xfs file system?

Ok, I still have many doubts but more or less 3 weeks to solve it and
test them on my machine, any help is appreciated, thanks

What do you need the backups for?
For disaster recovery in case of a fire?
For restoring files that were deleted or corrupted by mistake?

Is there any policy, e.g. a legal policy or an agreement with your users?

The policy will determine the backup schedule (e.g. every night) and the
retention period (e.g. 3 months, after this time files can still be
restored).

Well good question.
I think I should handle different situations. There could be a
periodic backup (no more than once a week) that stores data somewhere
else (over the network, external disk etc) and other backups which
stores different versions.

Now I don't know how I should do on a serious server, but maybe even
rdiff-backup or subversion could be fine to handle the different
versions of files.

What about the dat storage? Is it good?
Lvm can help me somehow?

In which file system should I store data / system? Xfs / reiserfs /
other?

Try looking at Amanda which is quite efficient at backing many
harddisks up to tape.

Last time I looked at it, is was a bit tricky to get things right but
then it just runs and runs.
