No two backup sizes are the same


#1

Checking backup size under statistics:
366GB

2018-08-12%2013_33_46-UrBackup%20-%20Keeps%20your%20data%20safe

du -sh
345GB

List of individual backups (added up) - broken database summaries?
45GB

Am I missing something?

No, you aren’t missing anything. Understanding the statistics that UrBackup shows is confusing, and I’ve frequently struggled to understand them.

I believe the Size column is reporting the data transferred from the client for each particular backup (the deltas), so this doesn’t necessarily tell you anything about the extra size on disk required by those changed files.

The Statistics page isn’t more helpful, in my experience. It significantly underreports usage for certain clients in my setup. How do the numbers in Statistics match your own tests with du?
