I have a problem on one of my backups.  
I use --keep-time = “1M” and the backup number is always 1!

Last successful run:Aujourd’hui à 11:21 (took 00:00:30)Run now  
Next scheduled run:Aujourd’hui à 13:00  
Source:18,86 MB  
Backup:5,35 MB / 1 Version

If there was no change in the source data, Duplicati will not create a new version.

You can change this with `--upload-unchanged-backups=true` such that each backup creates a new version if you prefer.

The number of versions in the Web UI will not increase if you start backups using the command line tools.See this issue:

Am I correct in assuming a high version count with low/no actual file/chunk changes is very unlikely to incur a database performance hit?

I know some people want hourly or even every 10 min. backups that could baloon some tables with `--upload-unchanged-backups` enabled.
