Thanks Steve, that's great feedback. Some snipping now, and new
threadslater:

backups to DVD.
Not mirroring your system disk is a bit dodgy. I'd've probably created a single
raid 5 over all of the disks, then partitioned it up. Booting off a raid disk
isn't too cumberome any more.
OK I'll put that on my list to look in to as well. Certainly this first
venture into raid was easy enough, 5 minutes with google was all I needed.
On my list to do or find out about or learn when the holiday is over:
- orange network on the ipcop box for the wireless network.
Orange is usually set up as a dmz, and wireless blue. Also, is your ipcop
installation up to date - I'm on 1.4.18.
By orange, I mean blue. If you hear me say airport, I mean hospital.
Hopefully that's clear ;-) I'm on the ipcop update mail list which
informed me of the latest update before xmas and I've been slack on that
- I'll be attending to that this week.
- rsync script for off-machine backups of changed files through the day
I find that a sata disk in a caddy is a really simple way of backing up - usb
can be a bit slow if you're throwing large amounts of data around: firewire is
better. These full-size external disk thingies ( eg from Western Digital ) seem
to be good value.
I'm one for simplicity in my backups. I prefer to tar all modified files, and dump databases. It makes for a simpler recovery if necessary. I also tend not to compress archives on busy machines: it takes a lot of cpu. When in a lan environment, it's no big deal ( and free ) to transfer lots of data at 2am.
tarring only (not compressing) is a change I'll be making this week too
- Chris suggested it recently too.
If, of course, you're backing up over the internet, then yes, things have to be
more complex to save bandwidth and money.
It's been more to fit certain sets of data on a DVD and stopping
compressing may require a revision. However it's better than the
failure of an archive due to an error in the writing which does happen
from time to time as I have discovered in restore tests. I have an
exterrnal hard drive that I'll make more use of but will look into those
caddies too.
- postfix / sendmail
imap email (and remotely)
- OpenVPN for remote access
- central management of users?
new threads or much later for some of these. Again, thanks for your
feedback.
Roger
Cheers,
Steve
