Backup

[joep]

At config centre>systems I can't find the backup file. Snapshots is not functioning.
So: how to backup my files? system?

For file backup I use "backintime" available via MCC (install and remove software).

For system backup I use Clonezilla. You would have to download the .iso and burn to CD. This will make an image file of your system that you can later restore if things go very wrong. I use this method weekly and it has saved me time and time again.

Hope this is helpful to you.

You should also take a look at http://redobackup.org/ which is maybe easier to use

Ok this thread is about backup.

If for example I've a DB that's a terabyte,
or larger, in size. It's 24/7/360 live and
moving all the time. You can't turn if off,
ever. How would you back that up? Don't
loose it or your job's toast.

RAID - and make sure you monitor the appropriate system logs so you know if a disk starts to fail.

But that answer assumes you really mean backup, not archive. If you want to archive the data, use a DB that supports replication, then take the slave DB offline long enough to make a copy to the media of your choice.

Very good start.

FWIW Computer Engineering 68 ( Hardware not software ).
I spent over 40+ years in the data storage industry then
retired in 09.

With a db that sensitive, lets say it's Ebay's db, why even
back it up at all?. Build your multiple RAID 6 lets say in
three's and mirror them. Also FWIW the Ebay system
is a Sun Solaris system. One box. And a very tough
one at that. With mirrored RAID storage.

Somthing as big as that would never just be one box, it would always be a failover cluster with some load-balancing.

The database is virtualized and spans 600 production instances residing in more than 100 server clusters.

I actually reached out and touched
one of those Sun Boxes some years
ago. You'd be amazed as to how small
they are. Many of the "servers" are
virtuallized. The fewer the boxes the
more reliable. If I remember correctly
the eBay box was about the size of
a double door refrigerator. The RAID
rack(s) take up the best part of a room.

Today I run a script file in /etc/cron.daily to gather
into one directory all my working files then roll that
directory off onto an 8GB USB drive once a week.

Everbody here who has a DB with terabytes in size, pls put your hand up! Pls keep inside proportions

We are talking about backing up a user system so the user will not lose his data by hd crash or whatever. Somebody who works professionally with terabytes in databases will surely not use any of the archive systems the initial poster is asking for. And vice versa.
