I have a customer who currently has a NetWorker V4.2B server on a
AlphaServer 2100 4/200 Digital UNIX system with a TZ877 (soon to
be upgraded to TZ887). This system is currently backing up a
mixed bag of UNIX and NT systems.
He is planning to either
1) Add a second TZ887 to the Digital UNIX system, or
2) Set up another NetWorker server on a Windows NT system.
He has a couple of questions in order to figure out what
direction to go:
1) Are the tape formats identical between the NetWorker servers
on Digital UNIX and Windows NT?
2) Is there a way to duplicate tapes on one server so they can be
moved to the other server and scannered in? Could he:
a) Clone the volume (he has heard that cloning is slow) then
remove it from the media database, or
b) Use dd to copy tape-to-tape,
then move it to the other system, scanner it to get the index
entries and go on from there.
Has anyone tried this?

if tape formats aren't not the same, there is a bug. Legato uses the same tape format on all servers for this reason. NT/UNIX tape format compatibility has been tested between NT Alpha and Digital UNIX. From there, the problem reduces to one of transferring tapes. | |||||

Cloning is the only safe way to make a copy of a tape. Any non-NetWorker tool may end up loosing some of the data off the end or have other problems. We can not support tapes copied with another utility and I would not trust them with my data. If they only need the tape on the second server if the first server is out for a long time then use mminfo to make paper logs of what's on what tape each day. These print outs can then be used to find the needed tapes for scanning if a critical recovery is needed before the failed server can be fixed. In general I think they would find it more useful to have one server with two drives then two servers. | |||||
