Right. These four jobs upload data to a single duplicacy datastore, named Cloud. .
In other words, there is a duplicacy data folder somewhere in you My Drive that contains the following folder structure
some stuff here
The four subfolders under snapshots correspond to your backup jobs/snapshot IDs. Right? If so, then this statement
is misleading: you are backing up everything into a single “folder” (aka duplciacy datastore). Chunks from all jobs end up in the chunks/ folder there.
And if you do that from multiple computers then you absolutely can hit that concurrency artifact from my previous comment.
Connect your google account to rclone, run
rclone dedupe and then try to reproduce the issue again. If it started working normally – then that’s what the problem was.
(Another possibility is that you are keeping your duplicacy datastore on a google shared folder, which has limits on the number of files, but seeing the sheer amount of chunks reported you are way past that limit, which means your datastore is in My Drive folder, and not shared folder, and therefore this is not a concern).
