I'm testing Backup Exec 2010 on my OES 2.2 NSS volumes. I bumped up block and buffer size for the tape to enhance backup speeds, which it did. I also reformatted a b2d disk with the max block size my backup server could create.

Now I can only restore files if I don't preserve the tree (path). If I preserve the tree, the restore fails with an "insufficient disk space" error. The entire directory path is created (I'm redirecting to another volume with plenty of space, which is what I've always done), but the file isn't restored.

Is this being caused by changing the block size on the tape?
