Paul:
On most of the VTLs I've used you set the size of the tape image to the size
of the physical tape you might export to (as a maximum) in order to
maintain compatibility with the physical tape volume. The VTL will only use
the amount of space it needs for the save even if it's set with a large
maximum.

1) What size do you create your VTL volumes?
Just large enough to include one nights entire save Or Do you go with a
standard size, nTB.
2) We keep 180 days of BRMS log data. Never have to use a native restore.

Using VTL instead of manual tape is opening up some options for us.
Especially with the though of a remote data center.
Remember when I told you that we have two data centers? One in Garrett and
one in Kendallville. Both in Indiana and only 17 miles apart. So we have a
third VTL at US Signal in Grand Rapids MI. That only replicates the mtrees
and not the individual volumes.
Well, our Garrett building data center, while newer, is a glorified closet.
Even so, it's getting so crowded there they are eyeing that space.
The thought process is this.
1 - Forget about the third vtl in Grand Rapids.
2 - Move all equipment currently in our Kendallville data center to Grand
Rapids.
3 - Move all Power 8 and other server racks from Garrett to Kendallville.
4 - Move remaining Garrett telco equipment to a room across the hall with
some noisy UPS that no one will ever tolerate as an office (at least since
my boss moved out of it).
We can easily consolidate the equipment moving from Kendallville to Grand
Rapids in a single rack. Before we do so we're checking with US Signal if
we use our rack or theirs.
Sure there will be a lot to make sure of but this ain't my first data center
move.
With the third vtl we've been testing the comm between us and Grand Rapids
and we're happy.
