I installed Duplicati and set up the files I want to backup, but I do not know how to configure it to use B2. When I run the backup, it does nothing (0 files backed up in 1 second).
Backblaze has a setup guide here that might help:
Nice info. Also make sure Source page is set up right, and check Filters for any excessive ones.
Show log page will summarize what it saw in Source. Finding 0 is rather unusual.
Thank you, both docs were very helpful. The first time through the configuration I totally missed the fact that the Destination is where I would specify B2. After reading the first doc, I made a second attempt that missed the capability of the Source Data to specify individual files. My third attempt was successful in backing up the 10 files I wanted.
I should have started with the second doc you listed. It would have made it easier to set up the B2 connection. I was able eventually to match the terminology of B2 buckets and keys with the Duplicati configuration terminology, but that blog doc would have saved me a couple of trial-and-errors.
