I am wondering how people use the freedombox backup feature.
The options I can see for backup:
make a backup now to local storage
add a backup location on local storage
add a remote backup location, with sftp
With the options 1 and 2, besides making the backup stored on a removable USB disk, that can be accessed from another computer when there is the need to restore, is there any other possibility?
The option 3 looks more useful, but one needs an sftp server. I did configure this several times with command line, while the goal of freedombox is to avoid this. Perhaps a solution could be to use another freedombox.
Is anyone using the remote backup location?
If so, how did you configure the sftp server?
Is anyone using local backups?
On a removable USB disk?
I used to have my FB set up like this on a RaspberryPi 2B:
SD card as root file system
external USB HDD as data location for various service and also as backup location
FB’s backup is using borg so the backup location on the USB drive was a simple borg archive. I never needed to restore anything(*), but if need be I could simply plug it into another computer and restore anything I need .
After a migration to new hardware (raspi 4b) I decided to also install the root & boot FS to the USB drive. SD cards do not have good failover characteristics and I’ve run into issues with them a few times over the years. So my new backup location is a separate partition on the (single) USB drive attached to my Pi.
However I am thinking about seting up a remote second backup, too.
(*) Correction: I actually used the restore feature when migrating to the new hardware recently. I had some issues with tt-rss, but aside from that, the restore worked fine. I moved the borg archive over to the new hard drive and used it as backup location in FB’s configuration - all backups showed up in the web UI as expected.
If there is a problem with that USB drive, isn’t there a risk that all partitions are affected, possibly making the backups unusable?
I had a number of times a freedombox (Pioneer with or without SATA disk) become completely inaccessible, so I had to remove power. Each time, I take the micro SD card to a computer to check the file system(s). Sometimes, it is fine, sometimes, it is not. If a file system seems to have a lot of issues (it happened several times), I do a fresh install and restore. I did one very recently.
I am currently documenting backup and restore, for myself and others. I have my working methods for the remote backup location, but I am not sure what others do, hence why I am asking.
Yes, absolutely. I do make verbatim copies of the backup archive on a separate hard drive, though. Not as regularly as my FB schedule, but definitely before major changes or at milestones such as having just successfully finished my migration.
And I fully agree that having an automated + remote backup is the preferable option. I do not have a suitable backup location atm, but I have plans to.
