Is a tool available to check the integrity of copied files?

Ah. I must have missed that. A small test could be done with a backup
of one text file that gets copied over and then changed in one
location before the comparison is run. Grsync catches such changes
here, but I'm doing my backups from one SSD to another rather than a
stick.
