if (for example) you have several TB of data on a home network where the
backups are stored on a USB disk attached to a consumer-grade NAS. It
also means your backups will be offline for the duration. In my case
this takes about a day, with the bottleneck being the single USB2 disk.

For my backup of digital camera photos and movies I compute md5sums for
each file using this little utility:

It has shown me that in the last month or 78 files have changed for some
unknown reason. Good thing I have an earlier snapshot to compare to.

For off-site backups I use Amazon Glacier and this command line client:

I've been living in Sweden for the last year and it sure is nice having
no-quota super-fast internet. Pushing multi-Gb tarballs up to Glacier is
quick and easy.
