I have all my family pictures and videos in my hard disk. To safeguard them, my backup strategy is to make a copy on an external hard disk drive and keep it in a relative's house far away.
As soon as new pictures and videos arrive, I will bring it here and backup them up.
Also, once every month or so, I want to bring it here and make sure the backup copy is intact. If something is wrong, I will buy a new hard disk or take necessary steps to make sure a second copy is made quickly.
I need help with this second part. How can I make sure that nothing is wrong with the backup copy?
Some things that come to my mind are:
- Somehow some files are missing.
- All files are present, but they are corrupted somehow (players unable to read JPG, MOV etc..)
- Hard disk sector level corruption.
- Hard disk hardware failure.
Except for the first thing, where I can simply find the no. of files and make sure the count matches, I don't know how to check for the other failure points.
How do I check all these? Is there anything else that I should check for whenever I bring it in?
It will be really great if one program or action can check for all these and report any problems with ANY of these so that I can go ahead with fixing them or making another good copy. How can make the whole process of verifying all these things streamlined?
1. I do not use any backup software. I create my "copy" by just.. copying the files.
2. I am using Windows 7. So any tools you may suggest must work with it.
