A message you do not want to see from your backup software

We just got the following message today from a well regarded commercial backup system that costs a lot of money:

* host:/filesystem save: path length of 1025 too long, directory not saved: /filesystem/long/dir/path/...

Path name length limitations; just what I like to find out about in my backup software. (I suspect that the limit is 1024 characters and that the path is not exactly 1025 characters, it's just that the 1025th character triggers the error.)

I'll look on the bright side: at least it told us about it. There are worse things that can happen.
