Enormous backup size?

Support
1

I’m trying Duplicati with B2 storage. I selected a bunch of files that can’t possibly be more than 2.5 TB, probably more like 1 TB, but Duplicati says it’s backing up 650 TB!!!

2664956 files (642.70 TB) to go at 836.02 KB/s

Is this a bug? Or maybe it’s due to following symlinks and backing up the same data multiple times? How do I find out what it thinks it’s backing up?

Also if I try to stop the backup, edit the configuration, and start again, it won’t start again, I get an error “The database file is locked database is locked”:

The database file is locked database is locked

This is on Ubuntu 18.04.02 using the latest .deb file.

I tried to select just 2 folders for backup, with total size of 3 GB, and now it says the backup size is negative!?!

6 files (-615 bytes) to go at 715.39 KB/s

Can you enable debug logging and provide the log file. Remove any sensitive info from the log before uploading.

5

Can you link to instructions on how to do that?

6

Execute the job as a command line and use the following options, log-file-level set to profiling and log-file option to send output to a file.

I haven’t figured out how to do the debug thing yet, but running more backups, I get error messages:

If I click on Show, it doesn’t show me the errors, it just shows me “Log data” with a list of dates, with no indication that they are clickable:

But they are. If you click on them it then shows a big dump of text:

Screenshot%20from%202019-02-17%2015-23-40

and if you scroll down enough, there are some nested brackets with this inside:

Errors: [ 2019-02-17 15:04:15 -05 - [Error-Duplicati.Library.Main.Database.LocalBackupDatabase-CheckingErrorsForIssue1400]: Checking errors, related to #1400.

This is a pretty bad user experience. Yet it’s the highest-rated backup solution on AlternativeTo, so the others must be even worse?
