Now I understand there's quite a bit of work going into backups just
now, and I too have a number of questions to add to Philip's:
o When is the new, fast backup feature going to be available?
o Will it work with NDMP?
o Will it work with Networker?
o Will it support backups to two concurrent local devices (2xDLT7000 at
the same time, for example)?
o Can DOT backup to 2 (or more) local devices right now?
o Can it do so under NDMP under the control of Netbackup?
o Will DOT be able to do backups to multiple local devices concurrently
under Networker?
o Can an F630 stream two DLT7000's concurrently using any technique you
care to name?
o Will the new fast backup technology allow for specific-file recoveries
or just full-filer-after-disaster recovery?
o Are the indexes of NetBackup or Networker maintained on their servers
even when backup data is going to locally attached tape drives?
o Would this remain possible with concurrent backups as described above?
o Does anyone have this sort of aggressive approach to backups already in
place?
We're looking to breach the TB barrier using 3 F5/600 series machines
in the near future and I want to be able to back each filer up no
slower than the current longest backup, which is just over 12 hours.
Ideally I want to actually cut the backup window and improve our
ability to restore data at the same time (because these are worthy
goals and because at this time the money seems to be available to do
the job 8).
