Per 5.0 release notes

The maximum backup size (per backup stream) supported for NetBackup 4.5 was
1 terabyte. By extension, this was also the maximum supported file size and
file
system size. NetBackup 5.0 extends beyond this limit with the capability of
taking
very large backups, with very large defined as over 1 terabyte and up to 2
exabytes
(2 million terabytes). This includes backup and restore when combined with
other
NetBackup features and attributes, such as TIR, raw partition, encryption,
compression, etc. With this new very large backup support, NetBackup 5.0
supports
file sizes up to 64 terabytes, and file system sizes up to 2 exabytes, for
all file systems
currently supported by NetBackup, on all operating systems currently
supported by
NetBackup

Subject: [Veritas-bu] NetBackup vs terabyte drives & filesystems



I recently came across this Veritas TechNote which mentions support for 2
terabyte files / 32 terabyte filesystems:
TechNote ID: 249916 - Addendum to the VERITAS Volume Manager (VxVM) 3.5
Release Notes for Solaris. New feature in VxVM 3.5 is 32-Terabyte volume
support, link: http://support.veritas.com/docs/249916 


We currently run NetBackup 4.5 FP3, which (we found out the hard way) has a
1 terabyte-per-stream limit. 

We installed an EMC SAN and several EVA SAN's last year, and now have
numerous multi-terabyte servers.  We had to enable multiple streams for
certain clients just to ensure NetBackup didn't keel over after pushing the
first terabyte.  Recently one group here started allocating individual
filesystems over 1 terabyte.  Just enabling multiple streams and using
ALL_LOCAL_DRIVES isn't going to cut it much longer. 

So, are any of the latest Veritas NetBackup releases going to be capable of
coping with the latest Veritas Volume Manager file/filesystem maxsizes soon?
