I have been getting complaints of slow backups from Mac client nodes.
I wanted to examine the possibility that this was not simply the whining
of a population already prone to whine, so I got a Mac OSX 10.3 G4 box
and put it on my desk, and installed TSM 5.3.2 client on it, and sure
enough, it backs up very slowly. They're not just whining; they're
right. A recent incremental took 11 hours, during which time it was
"inspecting files" at a rate of about 3 files/second.
Roger,
Would you believe that memoryefficientbackup is on by default? That is
usually step one for me.
This is average performance for my mac desktop on a 100Mb connection:
