File Security Under NT/2000

I am trying to back up my server, but there are no freeware products that will save the ACLs off the files on the backup. Tape backup is not an option—we've just invested in a CD-RW. How do you save and restore a particular file/folder's ACL?

If you were copying to another hard disk for NTFS format, you could use the XCOPY command with the new (for W2K) /O option to copy ACLs; or use the NT Resource Kit SCopy utility with NT 4.0. However, CDs don't use the NTFS file system, so you are out of luck there.

Basically, the only way you can maintain this info if you are writing files to a CD is to extract the information (with a program like the Subinacl utility that comes with the NT Resource Kit) and then reapply it to the files after restoring.

I don't know of a program that will do this for you. I know you said not to mention tape backups, but smaller backups are very inexpensive, as is a large second hard disk, and will save you a lot of pain and tribulation.
