I have a bunch of nodes on my TSM server (AIX 4.3.3) that are not
being used anymore (the machines have been de/re-commissioned), but we
don't want to just delete the backups. Instead, I want to export them
to tape and stick them on a shelf. This way, I can safely delete the
nodes from the TSM server, recovering a lot of disk space, and if we
ever need to look at the data, I can re-import the tape.
The problem is that the nodes range from 600MB to 9G each, and
I have an 8mm tape drive (5G cap) that I can export them to. If I
export the 600MB node to a tape, I am wasting a lot of space. The
export command will allow me to specify multiple nodes, so if I can
find a collection of nodes that just fits (hmmm... where is that
polynomial time binpacking algorithm I wrote back in college 8-),
then I can export multiple nodes to one tape.
This creates two questions. If I export a dozen nodes to a tape,
and then later someone needs data from node XYZ, can I stick the tape
in and "IMPORT NODE XYZ DEVCLASS=8MM_CLASS" and it will ignore the
other nodes?
The second question is this. Some of this decommssioned data are
filespaces on our file server. I have about a dozen filespaces on one
of the nodes that are not used anymore. However, they only amount to
about 1G of space. It does not seem that the EXPORT NODE syntax will
allow me to export nodes A, B, and C, and then filespaces D1, D2, and
D3 of D. Can I instead put in a 8mm tape, and then do:
EXPORT NODE A,B,C FILEDATA=ALL 8MM_CLASS SCRATCH=YES
EXPORT NODE D FILESPACE=D1,D2,D3 FILEDATA=ALL 8MM_CLASS SCRATCH=YES
Will this back it all up to the same tape and then allow me to
put in the tape and import one specific node or filespace?
