Why the long runtim?

My backup completed and it took 9+ hours. I look at the log file and it only accounts for ~4hours. Where is the other 6 coming from?


The three durations you’re adding up to get to ~4 hours (test+compact+delete) doesn’t include the actual backup phase. So presumably the other time was used in the main backup phase. Viewing the complete log may help to confirm this.

More complete backup summary? gives some hints on how to read the complete log.
I think the report is organized around the log data, with only “special” sections shown.
Implication is that rest is backup, and note that the Time section shows total duration.
