As bubba is a "server", it is the central store of users information (ok family information.)

It needs to back itself up like a real server, probably to a USB disk or a simple NAS disk, unattended. Not backing up to a PC etc. at the users request. We all forget!

Saying that, I ordered my bubba yesterday

There's already a number of incremental backup solutions using Rsync that will do this for you. Look around, there's one one these pages here. I'm mysql currentlty also working on a similar solution that can hopefully integrate into the bubba web-interface at some stage, so it can be used by non-hackers also. An optimal solution would be to have some backup option shipped with bubba. Getting this completely problem-free (which is required if it's to be shipped standard) is a lot of work though.

I've just bought a Qnap TS-209 pro for work,
Now I realise it's a different product for a different area.

One of its web based options is to set up syncing for a qnap directory to another share on other disks on a schedule.
You can add as many entries as you like for each seperate user, or area of the system.
Nice n easy, I can show a screenshot of the interface if anyone is interested.

Not complaining too much though, it does what it does and no more. Not like my bubba

Could you elaborate on this please? What backup options are there in terms of shipping?

Personally I would just like a piece of software for Bubba that mirrored its drive to another drive on the network. Is that possible?

Simply mirroring is super easy, but that is not the same as a backup! At the moment there are no shipped backup solution, but anyone with knowledge of unix shells can use rsync to copy to an external drive.

The main issue with backups that everyone here keeps on forgetting is that the backup drive needs a capacity that is significantly larger that the size of the drive it is meant to backup!

Good post Ubi,
but for the ignorant like me ??
Did you mind to post a sample of the rsync
Thanks.

Is rsync intelligent enough to copy changes only, or is rsync simply just a copy, where you have to delete and start again each time?

Can you rsync across to an NAS?

I am using rsync and autofs to backup important folders to an 8GBusb flashdisk.

Basically my rsync script runs every 12hrs using the crontab. It rsync the the selected folders to my usb flashdisk.

This is my backup script.
rsync -avr /home/work /var/autofs/removable/usbdrive/backup

What it does is copy the /home/work(this is smb shared folders) to /var/autofs/removable/usbdrive/backup which is automounted. I decided to use autofs for the benefit of easy flashdisk access. No need to mount/umount.

My crontab file goes like this:
0 */12 * * * /usr/bin/backup_script

It runs the above backup script every 12hours.

I know if you rsync between two linux machines with it installed, it's intelligent and hence very quick after the initial copy.

I have no idea if its done to a seperate non intelligent device.

I'm sure thats all the Qnap does. You set folders to copy from , folders to copy to (with login details of the samba share if necessary.) and a schedule.
But it makes it MUCH easier for most people to use.

Righto.
First of all, the manual for rsync is quite easily read (especially the extended bit at the bottom): http://optics.ph.unimelb.edu.au/help/rsync/rsync.html, so give that a read.

!!One thing to remember is that rsync always syncs one-way, never bidirectional!!

For an example command: my *guess* here (as I re-invent my rsync lines everytime again) is to simply use Hope this helps, let me know otherwise

Thanks Ubi,
One way is OK
