[Veritas-bu] Writing files to tape in WINDOWS...

"The LAN group want it to run so that D:\ get 2 drives"...
what exactly are you asking (or better yet, what specifically are they
asking for)?
half of D:\ goes to one drive and half goes to the other?
stripe across two drives and have D:\ go to this "fast drive" because
backups are too slow?
backup all of D:\ to a drive and "mirror" this to a second drive for
redundancy?
If they are a Windows group and are familiar with another product, they
may be really asking "my backups are too slow, help me speed them up". In
the past, the application they worked with (Arcserve supports this) may
have supported tape RAID, or RAIT as some vendors call it, and they may
have striped across two drives to speed up backups.
If they're asking for 2 drives because they want to "mirror" the tape
drives (as they did in the past using a previous backup app... again RAIT)
then you probably want Inline Tape Copy. If you break the data on D:\ up
into two streams so each stream goes to a different drive (and it may not
depending on MPX settings), this isn't what they want.
You need to find out WHY they're asking for 2 drives and then you can help
them.

Subject: [Veritas-bu] Writing files to tape in WINDOWS...
Okay this is directed to you windows folks...
I have been handed the project of backing up the LAN.
My env is NBU 4.5 M4 Solaris 8 to a L700 Lib...
I can do the backups and they work. The LAN group has informed me that
they
want the files/servers to be able to write to multiple tapes at the same
time....
Example:
Server A: & B: Win2k
files are D:\ and F:\ as well as E:\
I set up the multi streams but it is only writing to one drive..
The LAN group want it to run so that D:\ get 2 drives and so on...
Please help because I do not do Windows...
Thanks...
Travis
