We are in the process of totally switching to veritas 10g for all backups. I am not sure of the format that veritas uses. I do know that there is a linux agent (not sure if that comes with it or is an extra). Veritas will run on a win2k3 server and populate a tape library. I was asked if it was possible to test the backups on a linux backup server. Meaning I was going to set up Etch box and test backups with it if it was possible. I will have to check into the veritas format, unless anyone else knows if this would work.

Longer answer, it depends on the backup/archiver tool used. For example, if you perchance have Cygwin installed on your windows system and used one of the tools that are common to it and UNIX/Linux (tar and cpio come to mind), the answer is an unqualified yes. More likely you used a Windows tool, which probably has a proprietary archive format, so it can't be read from a Linux box. Or, you may have used a tool that's proprietary but that has both Windows and Linux versions. This may work. Then, there's the question of whether the backup is an image of the filesystem itself or just copies of the files. If it's an image (a 'true' image, such as a 'dd' would make), then you might be able to use dd to read the tape into a regular file on the Linux box and then mount that using the loop back device feature: dd if=/dev/tape of=/path/to/file bs=10k # or something like this. mount -o loop -t ntfs /path/to/file /path/to/mount/point Bob smime.p7s Description: S/MIME Cryptographic Signature
