VLS to MSL "tape" copy
We use ArcServe to run our backups nightly to a HP VLS6227, which is configured to emulate a MSL6000-Series Tape Library. I have 60 Cartridges created, each sized at 100GB.
I am looking to find out how to best copy/move these data to the physical MSL6030 tape library that I have. It is a 30-Cartridge Library, with two LTO-4 tape drives in it. These devices are fiber-channel connected to a Storageworks 4/8 SAN Switch.
I have run tapecopy commands at a command line prompt from the backup server successfully, but it does not seem to take advantage of the second tape drive, using only one drive. I have had no problems getting the 100GB cartridges to stack onto a single LTO-4 cartridge until it is full, but I would like to shrink the amount of time needed to transfer these cartridge sets by using both drives.
Is this possible? Can I simply execute another tapecopy command from a second command line window? Are there any other utilities that can preserve the CA format but allow me to do this, if CA can not do it natively?
And finally, if there are any non-CA readers looking at this, can I accomplish this task better with some other product? Obviously, this would involve an overhaul of my entire backup software architecture, but I'm at a point in my maintenance agreements where this would be feasible.
Thanks.

No need to use tapecopy ARCserve 12 supports a VTL as a source, or you can add migration to the job so it will all happen automatically.

What if I already have a bunch of data backed up to the VLS that was not configured to use staging? Is there a way to Migrate these data to the physical tapes (MSL)?
That was covered by the first statement, 12 supports the VTL as a source.
If you have not been keeping current with the updates that is strongly recommended.

I do not see an option for my VLS in the Source Tab of the Backup window.
That would be a great option to have available, but I'm not seeing it. Perhaps an option that I do not have installed? I have the SAN Option installed, which gives me the Tape Library Option as well.
Thanks.

Contacted CA Support to further investigate using the VLS as a Source in a Backup Operation, they indicate that it is not possible.
So, aside from staging, do I have any other good options? The tapecopy utility is a mess.

Storage
Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.
