Backup Central

I have a mount point that that is 1.5TB. I have almost that much change
each night on the mount point. The mount point has only one directory with
many files. File names are constantly changing. I am backing up to IBM
LTO-2, but I am not getting the performance, because I need multiple
streams. Need to increase streams on the mount point. Does anyone have
suggestions?

You could create a few instances of the client, each with a directive
looking like :

<< "/some/directory" >>
null: [!a-bA-B]*
ignore

for the 1st one, that wouls cater to the files beginning with a or b

<< "/some/directory" >>
null: [!c-eC-E]*
ignore

for the 2nd one,

...

<< "/some/directory" >>
null: [a-tA-T]*
ignore

for the last one.

Put each of these instance in its specific group and start the groups
together, without saving the client index.

In addition, you would have another instance with a directive like :

<< "/some" >>
null: directory

to save the remainder of the client and the index.


I use someting similar to backup a somewhat large CIFS share with a lot
of directories at the first level from a Celerra without NDMP. It is
indeed noticeably faster than one stream but a little awkward.
