I recently built a new PC and have been trying to figure out how to continue using the backup sets I’d used previously on my old computer. The files are in exactly the same location with all the same names so I figured I could just rebuild the database and continue.
The first issue is that the database never seems to finish rebuilding, I left it to run overnight and it never finished. It’s only a backup set of 380 GB and it should only be going to my local NAS.
In investigating this I noticed that during that time it had averaged 70.28 MB/s writes to my brand new SSD, writing out a total of 2.3 TB or 6.2x the actual size of the backup set before I killed the process. These writes were to both C:\Users<user>\AppData\Local\Temp\ and to C:\Users<user>\AppData\Local\Duplicati. It ‘only’ wrote out a total of 7.16 GB to temp and 942 MB to Duplicati’s folder. I guess constantly overwriting itself.
What am I doing wrong, and why is Duplicati writing so excessively?
