# 3483 Backup and Restore Not Using Correct Backup Headers

---

I've just encountered some strange problems that I've never had before. And because it has to do with the Backup/Restore features it is rather unsettling because I'm always nagging my customers to back up regularly using my app's built-in utility (which just makes DBISAM Backup/Restore calls.)

When I try to restore a backup file (.bkp) that was created with a slightly prior DBISAM v4.30 build (prior to 6) I get an error saying "Cannot read Backup Info". This happens when I use MY app (compiled with 4.30 build 6) or DBSYS.exe of the same version.

If I revert to a build of my app that was compiled with DBISAM v4.30 prior to build 6, then I am able to restore that very same backup file that fails when I try to use DBSYS.exe 4.30 build 6, or MY app that was compiled with same DBISAM version.
