====== Duplicati ====== I tried to use this backup solution but ended up running into obscure errors that halted the entire backup process: "Abort due to constraint violation UNIQUE constraint failed: FilesetEntry.FilesetID, FilesetEntry.FileID" There is an [[https://github.com/duplicati/duplicati/issues/3753|open issue]] from 2019 about this error. Even if it was fixed, though, the more alarming thing is that the system cannot gracefully recover. I used the free version of their monitoring service -- which they sell as a solution to monitor the status of backups -- and it did not report any errors from this. So not only does the solution not work, the monitoring service doesn't either. The backup I was trying to perform had approximately 22TB of data across 6.5 million files. It is not practical to fix individual file compatibility issues to complete the backup successfully. {{ ::duplicati.png |}}
