Verifying physical integrity of backed up files
by SlowCoder from LinuxQuestions.org on (#5K89M)
I bought a new USB drive for primary backups. I used 'rsync -av src dest', and all appears to have copied over.
I want to verify the backup files are actually stored correctly (no on-disk errors), and are exactly the same as the source.
Searches bring up rsync -c or --checksum. But diving into it, this function only works on the sending and receiving processes, not the files after they have been written to disk.
How can I verify the checksums of all my backup files against my source files, post write to disk?
