Hi All,

If you are using a single rsync process, then it can take many hours.
I'm going to assume your directory has many files in it and/or directories.
What you can do is create many rsync tasks point at file 1, file2, etc or dir1, dir2.
So one rsync for every directory or one rsync per file or files.
Renice or set the nice number higher so the rsync gets higher cpu priority.
Don't use the -z option when transfering between disks on the same system and don't use the -v option.

Example:

rsync -a /data/dir/file1 /data2/dir &

rsync -a /data/dir/file2 /data2/dir &

And so on.

regards
