Hi,

what is the best 'streaming mode' NOT 'shoeshine mode' backup software and hardware setup for a single Netware 6.5 with 200GB of kind of small word files.

We are considering not only the software (CA, HP) but also the drive setup (LTO directly attached to the server).

your advice pls....

I'll confess that I've never heard of those terms being used to describe backup software. Could you elaborate?

In general, your backup device should not use the same adapter as your disk subsystem. So if you have a SCSI disk subsystem, let's say, you have your backup device on a different HBA, not the same HBA as services the disk subsystem.

Your backup software should understand NetWare Target Services Agents (TSAs) - this is an important question to ask any vendor. It should see NDS as its own separate object to be backed up (using TSANDS). Similarly, it should interface with TSAFS to back up the file system. These are questions that any backup software vendor should be able to answer positively, or you're not interested in them.

I'm aware that Tivoli Storage Manager (TSM) and Veritas Backup Exec both fit this criteria in their latest revs.

You are probably also interested in Open File support - this may take a 3rd party Open File Manager; the backup software vendor should be able to suggest some, if they do not natively support it.

Streaming mode is when a tape is constantly written to. A lot of stop /rewind/start will drastically decrease the lifetime of a tape-drive.

What about CA Brightstor Arcserve 9? Some vendor claimed it can't be done with this software version. Version 11 is not yet available for Netware.

Thabks.

Ah. Now I get it. "Shoeshine", that's funny.

I confess to never having paid attention to the method of tape access. Of course, for the past few years, we've always had tape libraries, so it was all hidden.

Yes, ARCserve does support NetWare, and I'm fairly sure it supports TSAs at V9.

I really think you'll have to ask individual software vendors about the "shoeshine" vs. "streaming" mode. I suspect that has more to do with the hardware than with the server.
