Does kopia snapshot verify write to disk?

Hello all,

I’d like to use `kopia snapshot verify --verify-files-percent=2` (in a linux/raspberry pi) to do periodic checks of data consistency in a repository stored in the local filesystem.

When I run that command, I see not only IO read activity (as expected), but also IO write activity.

Since nothing else is doing IO writes at the moment I run that command, I assume it’s kopia writing to disk.

With that assumption in mind, I kindly ask for your help with some questions:

  • Is it possible to do that verification without writing to disk? this is a local repository, in my case.
  • If that’s not possible, where in the filesystem kopia writing to? to its cache directory? somewhere else (e.g. `/tmp`)? can I configure where it writes to?

thanks for your help,
