In past I really liked the backup possibilities of TWRP but as far as I know there is no officially supported version of TWRP for the FP4 available and you even loose warranty when installing it…
Is there any alternative custom recovery available for the FP4?

What do you want to achieve with a custom recovery? Flashing something will not void warranty as long as you dont brick the device with it and if you need Belp from support you might need to go back to stock.

As I said I like the possibility to backup my phone which is not possible in stock recovery. I did that quite often in the past prior to switching to new LineageOS versions and it’s really comfortable and easy to use. And I have local backup, no need to upload everything to Google…

Some comments
Locking and unlocking the bootloader will wipe userdata as well, yes.
Mostly because TWRP (so far) has no access to encrypted userdata, so it’s not really that useful for backups. All the custom ROMs ship their own recovery, which takes care of your basics like sideloading and wiping data.
You can do “interesting” things with TWRP and adb. But in the unlikely case you have to, you can just fastboot boot TWRP, instead of installing it and causing yourself another hurdle for OTA updates.
I think ADB backup is doing the same, however
Good day!
I used my FP4 for a couple of weeks now without issue. It was rooted using Magisk which also worked fine untile the last update to A.099 after which Wifi stopped working, it didn’t want to activate for some reason.
So I made a backup using
adb backup -apk -shared -all -nosystem -f backup.ab
and uninstalled Magisk. After that I got stuck in a boot loop. Switching the active slot and flashing the factory image A.064 brought me back to where I came from.
Up to this point everything i…
I’m not aware of any recovery doing what TWRP could do in the past.
Overall reg back-up there are several topics in the forum, that might give further hints.

I have performed backup/restore with TWRP at least with these devices in the past:
Samsung S5
Samsung S9+
Samsung S10
Xiaomi MI5
Xiaomi MI8
I assume it is not yet working with FP4 due to encryption issues, with the above mentioned devices it worked like a charm.
That is correct. You can follow the progress to get TWRP (fully) working here
Here you can find TWRP (TeamWin Recovery Project) builds for the Fairphone 4.
Please remember that TWRP is not officially supported by Fairphone!
You can now find TWRP directly on twrp.me !
Known issues:
Encrypted userdata not supported
Vibration not supported
Other undiscovered things?
Please also note that Android security features like AVB (Android Verified Boot) & dm-verity might make your device unbootable if you tamper with some partitions. Keep your important data always backed up …
