1.
Yes, you can restore your TSM server with a single drive.
Just the same procedures you would use at a DR site with a library.
Install TSM server code on your machine
Define a library with TYPE=MANUAL
Define your 1 drive to that library
Use the admin command line to open a tape console (or you can query the
activity log every few minutes)
Run your restore DB
When the server needs a tape mount, you get a prompt on the tape console (or
activity log) telling the human to insert tape xxxxxx in the manual drive.
It will be tedious, and slow. But it works fine.
2.
In theory yes, but not usually in practice.
Backupsets were created originally with the idea that you could restore them
using only the client, without a server.
And that was done back in the day with the expectation that you would burn the
backupset to a CD using the server, then read it using the client's CD reader.
And it worked. DVD's, zip drives (remember those), and flat files are also
supported.
But these days most clients' backup data is too big to fit on a CD, and when
are you going to have time to burn it?
Better recreating the server and restoring the backupset that way.
Gotcha:
However TDP data isn't supported on backupsets.
So usually you'll be better off just doing that extra periodic full backup,
under a different client node name, and taking that set of tapes with you.

Subject: [ADSM-L] single drive restore possibilities
Hello All,
Thanks for your help!!
I have a client that selected TSM to replace their CA/Brightstore product.
When we showed up for the kickoff meeting, the IT manager said that he wants to
be able to create full backups of his mission critical servers when a hurricane
enters the gulf and wants to be able to take a single drive with him to an
alternate location to do his restores. He is adiment about not having to have
his full offsite copy pool with him to restore his mission critical systems. We
tried to explain how TSM prevented the need for second guessing disasters but
he wouldn't bite. He stated that he is willing to have someone feed tapes into
the single drive for however long it takes.
I have always been with large organizations that plan on restoring their TSM
server first and then all of the clients during DR testing for the real thing.
I don't know of any way to do this with since TSM wants a drive to be assigned
to a library.
I thought of exports but that also requires a TSM server.
1. How would one use a single drive to restore the TSM server first and then
the clients? Is this possible at all?
2. Is a backupset a viable restore option without a server?
I have read up on backupsets but the doc is not clear as to what is required on
the client. I suppose an adapter of some sort (scsi or fiber) a cable, a
drive, an installed OS and TSM client and then restore directly from the
backupset tape using the TSM b/a client.
Any light shed on this situation would be appreciated
Regards,
Nicholas Rodolfich
