Unable to resume backup which is mentioned in the faq https://attic-backup.org/faq.html

Running Attic 0.14 installed with pip3 on Ubuntu 14.04 LTS 64bit

1. Open connection to SSH (in my case a Synology DS411j NAS):
   sshfs [email protected]:/homes/admin/backup /mnt/backup
2. Start a long-running backup job on Ubuntu to an initialized remote repository over SSHFS:
   attic create -v -s -c 30 /mnt/backup/test3.attic::test-6 /mnt/public/testar
3. Wait for a minimum of 5 minutes (or specify a shorter period of time with -c parameter above)
4. Reboot NAS
5. Attic crashes with the error message below
6. Check backup size on NAS which has increased: du -d 1 -h .
7. Searching for .snapshot doesn't result in any hits, neither at source or destination
8. Re-opening connection and starting the backup again results in uploading all data again

Thankful for swift response as this functionality really is important to me when doing long backup sessions. If more information is needed I'll be glad to recreate and send it over. Thanks in advance.

Regards,
Stefan
