Hello
just recently experienced that files with a length of zero bytes
act like directories : Corresponding to the platform
and the type of filesystem those backed-up 0-byte files are moved
- directly into the tsm-database without touching
the 'destination-pool' if the access-control-entries is not too large
... for example for solaris-with-ufs
- or it moves those 0-byte-files also into the destination-pool
because the place for the associated acl-entry is too large
... for example for decunix-with-advfs or windows
for aix ... ? I just don't know.
I wanted to know from the service if there is a kind list of
Platform/Filesystem-Type and the corresponding behaviour
( 0-byte-file moves to 'tsm-database-ONLY' or
moves 'also-to-the-destination-pools' ) what happens to those
0-byte-files being backed up. The answer was that there is no such
a list.
My question was just to preview what happens to those files and
...maybe thats not what you want to know ...
