Although your environment is significantly larger than ours, if
I was in a position where I could setup a backup environment from scratch I would
seriously consider if I really wanted to invest any more money in tape. We
were writing all of our data to LTO2’s 2 years ago and since then we have
got rid of tape completely, backing up all of our data using 2 appliances from
Data Domain which then replicate (and deduplicate) all that data to 2 more like
boxes at our DR site. Removing tape from the equation has significantly shrunk
our backup windows and reduced our RTO’s and RPO’s.
I understand that disk based backup isn’t for everyone but
now that NBU 6.5 has introduced it’s OST option, it’s even easier
to manage replication through the NBU interface. You could also think
about utilizing your existing tape infrastructure for offsite tape copy once
the data is duplicated at your DR site.

I
have a question I would like to pose because I respect the vast amount of
knowledge
associated
with this forum. We are creating a new backup environment due to some changes
Currently
we will be backing up about 40 terabytes of data with a foreseen growth of
30-35% of data annually.
Data
being backed up includes, Windows File systems, Unix File systems, Exchange,
Oracle and SQL.
Having
a Production site and a DR site using present day Best practices and current
available hardware
what
strategy would you use to set this up? This is even considering purchasing a
new library and using LTO4 drives.
The
backup system will have a dedicated connection. We currently have 8 HP
prolient servers as our media servers
We
have some thoughts as to how and what we will do including using vtl's and
replication for the catalog
but
since this forum has so many experienced people I want to get some other
professional opinions.
If
you could set up (from scratch) a Production backup site and DR site based on
those data numbers which hardware and strategy
would
you use considering future growth?
