there are a couple of discussions around backups. This topic came up for me now that there is another big release of Fairphone Open OS. Btw., thanks alot to bringing new major releases to the FP2!
But updater now warns that making backups is of the essence. Although this looks like Captain Obvious, and I do make regular backups of my Windows and the Linux machine.
But making backups is easy on them. I use Linux for both Win and Linux to backup entire filesystems simply with dd, and every now and then I push new files into backup Zips. So I do not actually need backup SW.
On the FP this a totally different ballgame. In the past, I did some with the built-in Nandroid, but one cannot actually call that user-friendly (or at least easy to start).
There is no “backup guide”, a document that tells you what to do. I understand that there won’t be a “one stop shop”, so internal data and SMS need some special treatment.
I don’t trust clouds when they aren’t mine (I can use the Owncloud of my employer, whom I trust, but I won’t trust Google. That is why I use FP Open OS…), but this exludes most non-FOSS backup apps.
Oandbackup I used to have, but at some point I deleted it, and when I now re-install it, it complains that it cannot find oab-utils… In F-Droid, Oandbackup is two years old. There is a newer OandbackupX which claims to be the successor of Oandbackup, but that simply complains that it couldn’t get superuser rights and immediately terminates without doing anything.
It would be a good idea if someone could write a primer on how to backup FP Open OS, which does NOT start with “Use Google” or uses SW that won’t run unless being executed as root (and if such SW should be encouraged, then please supply instructions on how to run them as root).
For a major SW upgrade first I would need a backup that could deliver a bare metal recovery to the prior state. And that has to be complete without exemptions.
Less important are selective backups, but they could be useful in the long run. The FP2 carries a slot for SD cards, and I have 128 GByte in there, with > 60 GBytes free.
So for ease of use AND performance I think a backup onto the memory card would be the best way to do. Those can then be later copied onto the PC either with the file transfer or adb.
On Linux there is Timeshift which only makes delta backups (only what has changed) so even several dozens of backups won’t fill up your mass storage → You can run this for a considerable amount of time with no external storage whatsoever…
Thanks for any help.
