#Error All Folder pairs are invalid or inaccessible Hybrid Backup Sync

[rafaelb]

Hi all,

Local backups to 2 USB drives worked the first few times and then suddenly it all stopped working with a #Error All folder pairs are invalid or inaccessible. One of the drives on USB 1 is a WD My Passport 0820 and the other WD Elements 25A3. Both formatted as EXT4. TS-439ProII firmware 4.2.6 Build 20200821

Given it was working little lost on how to fix it...any help appreciated

Hi,

Looks like the same issue as I reported in this topic;
viewtopic.php?f=15&t=158536 - HBS 3 Update broke backup of encrypted folders

With the last update of HBS3 I think they broke something. Guess only option is waiting for an update that will fix it again, since rolling back to earlier version is not working unfortunately.

I have raised a ticket, fwiw.

Had an update on my ticket today. My RTRR server is running on an old TS-212 with 4.33.1432 firmware which is the sync destination. HBS3 jobs are built on my TS-451, the sync source.

Here's the response from QNAP:

Our team has checked.
It is a bug in supporting an old RTRR server; when the destination folder name contains "space", the job will fail with "invalid folder pair".
Our team has tested, created another job "qnap_test" to verify it (destination folder name has no "space"). It passed.

We will fix this issue soon. The workaround is to change the destination folder to be another one without any "space" characters.
