backup with deja dupe


Hello

I am trying to back up my full Linux OS which is on a USB. It has been installed in one partition (root/). I know I could do a separate home but maybe later when I have more experience.

My question is if I backup home in deja dupe on a external USB, and should I have a massive fail in the full OS, will I simply be able to restore the home folder in my new install? I have read many have permissions problems and it won't restore.

This question is perhaps in the wrong forum - I will close and re-post in another form.

No, what you should have done is click the "Report" button and asked for it to be moved.
Probably won't help - in excess of 300 reads, people just don't have the answer for you. Test it yourself and see.

I found individual restores from a deja-dupe backup (without using deja-dupe) to be ridiculously difficult. Wasn't my system, but convinced me never to use it. YMMV.

Thanks Syg00 - It's what I thought. Any suggestions for other reliable easy backup software?

I only looked at deja dupe as it seemed easiest. I am a little concerned about trying a test backup with deja dupe on my running system in case it destroys my home directory.

There are a bunch of different solutions - I use several. You need to define what you want:
- a "one time" backup
- a single backup updated each time you run it
- a "base" backup plus changes since the last run
- multiple copies
- network backup or local (say USB)
- how often
- automatic (time based) or manual
...

Answers to the above will limit the options. I personally avoid GUI solutions and script what I need - for you something like timeshift might be a good fit. I'm not sure it backs up /home by default but you can certainly define what you want.
Also be aware that there are directories you won't want backed-up - .cache is a prime candidate to exclude; it always big (Firefox e.g.) and always changes, so will be constantly selected for no reason.

BTW, take off the [SOLVED] - it might dissuade people from looking at this thread.

That's good guidance.I just had a quick look at time-shift and it looks somewhat better than deja-dupe - ie more options.

I don't want a single backup (with the whole thing updated each time I run backup). It would take too long.

To try and define what I want:

- incremental backups to a base backup
- backup to a usb
- daily backup
- automatic
- On a complete system failure I would launch a new OS of the exact same as the original (install the backup/restore software) and try to 'restore' from the backup USB.
- 'idiot proof' (but I know that's a long shot).
- I can see restoring the home drive can be a long haul - so ideally the option to restore the home or just system directories.

Look at rsnapshot, which uses rsync under the covers. It's designed to make incremental backups.
It's not GUI, tho.

I use backintime for just this purpose. Meets your criteria, including the "idiot proof" spec. Plus, it's just a front end on rsync and the backup store can be treated as regular files, so if you just need one file, say a config file for scanner, you can just drill down through the backup and do a straight copy of that one file.

Handles hidden files, the default excludes are sane and I've used it to restore my /home directory on many occasions without incident over the last several years. Does a good job with retention policies, so you can control the size of the backup store to fit your needs.
