I’m new to Duplicati (and please forgive me if my Google-fu has failed me) and I’m having trouble completing a backup job. System is a Mac Mini with 1 internal and 1 external drive running 10.10.5 and I’m running 188.8.131.52_beta_2017-08-01. I’m backing up to Backblaze B2. The backup failed (again) with after running for 4 days. I’ve successfully run Duplicati on 4 other Macs for other family members (with much small backup volumes).
I originally tried backing up everything with a single backup job (> 800GB) but after that failed a couple of times I read that the # of files being backed up can be an issue so I split the job by disk. The backup of the internal drive succeeded (source 29.20 GB). I started the backup of the external drive with a subset of what I need backed up and it worked (275.83 GB) at first. When I added to the external drive backup job (>400 GB) it failed with <14GB remaining with a file not found error (the complete log message is pasted below).
Am I hitting the # of file limit again? I’m curious as to why a file on /var isn’t found. Any suggestions are appreciated.
