In 2013, I bought a MacBook Air with 128 GB space. At the time, it was enough but since we got our daughter, my camera usage exploded.
So, I'm saving my stuff to an external harddrive. All fine and dandy, it's being backupped. However, I'd like to take a bit of extra care and make sure my files are protected with a checksum.
I first found md5 which is included at the commandline, and md5deep (via Homebrew) that can checksum whole directories. Later I found par2, which lets you repair damaged files at the cost of 5% extra disk space.
However, the par2 commandline tool works per file. And I've got hundreds of folders with pictures.
I'm looking for something like par2 (preferably commandline, but GUI is okay) that can work on a whole tree of folders. Anything like this?
