We would need a bit more logs to understand what is happening please. Send them complete and compressed please.

I have CENTOS7, with mondo-3.2.2-1.rhel7.x86_64, mindi-3.0.2-1.rhel7.x86_64
and mindi-busybox-1.21.1-1.rhel7.x86_64.
Use the following command for prepare USB stick aith archive:
mondoarchive   -OU   -l GRUB  -s 8g -f /dev/sda -d /dev/sdb -G

After long run command failing with

---promptdialogYN---1--- Failed to create USB #1. Retry?

In logs I see:

DBG1: [Main] libmondo-archive.c->make_usb_fs#1532: WARNING - make_usb_fs
returned an error
DBG1: [Main] ../common/newt-specific.c->fatal_error#304: Fatal error
received - 'FAILED TO BACKUP'
DBG3: [Main] ../common/newt-specific.c->fatal_error#320: OK, I think I'm
the main PID.
DBG2: [Main] ../common/newt-specific.c->fatal_error#327: I'm going to do
some cleaning up now.
DBG4: [Main] ../common/newt-specific.c->fatal_error#328: killall mindi 2>
/dev/null

And USB stays mounted:

/dev/sdb1                7.5G  4.0K  7.5G   1% /tmp/mondo.tmp.hWngNU/usb

Any ideas why it fails?

Hello,

yep sounds correct due to the lack of support.

That's "easy" to deal with. Add to your /etc/mindi/deplist.txt file all the tools you need at restore time. 
You would also probably need a kernel module, so you should also add it to /etc/mindi/mindi.conf FORCE_MODS variable.

Then, if you tell me what steps you have to do at restore time, and alsoprovide the archive log, I could add that to what mindi does so it's performed more automatically.

You're lucky, I'm not drinking beer, but eat wafles ;-
Hopefully see you another time.

Greetings,
Bruno.

As I've ever done anything to support it, I'd guess that the answer is no.
Now I'd need to look at it more closely to provide a better answer.

If your FS were decrypted, then you have a correct backup. However, it won't recreate crypted FS at restore time.
As I see you're in Belgium, I'll be at Fosdem this week-end so feel free to see me there if you're around yourself.

Best regards,
Bruno.
