disk space requirement in using rsync

[dywang]

hi, there,

I understand that rsync need about 100Bytes for every file to be transfered
in order to build the file list.

Could anyone tell me where this space is needed, on the machine where rsync
initiated, or the remote machine, or both?

e.g.    at BOX A:
Box-A#rsync -avz -e ssh dir-a someone@Box-B:
or
Box-A#rsync -avz -e ssh someone@Box-B: dir-a .

so in the above example, which box needs the space to build the file list, A
or B or both?

thanks

wang
