Yes, that helps me further, but what could be changing my files ? My backups have never left the phone. I've never even opened them. Let me ask you this. If I mount my SD card to my computer and mess with other files, could that possibly corrupt my backups ? Should I transfer my backups to the computer & just leave them there till I actually needed them ? I'd like to leave them on the phone but not if they're going to keep getting screwed up.
Let me throw a scenario at you.
Say I do an MD5 checksum and copy the number shown on a particular backup. Later when I try to reinstall the backup it comes up MD5 mismatch. Technically I could insert the copied number to the mismatched file, replacing the 1 that's there, and it would then install ? Not that I would ever do that. Just trying to wrap my head around this.
Downloaded your new app version, haven't played with it yet.
You've been very helpful explaining this for and I think I almost got it. I won't stop till I know it.
Thanks for the help Scary Alien.
Doogald: Your explanation also helped. I was in the middle of reply to Scary.
