Archiving, compressing and copying large number of files over a network

I am trying to copy files exceeding 500000 (around 1 TB) , through ssh however the pipe fails as I have exceeded the time limit for the ssh into the remote computer,

so I moved on to archiving and compressing (using tar and gzip) all the files on the remote computer, however even if i leave the process in the background, since I exceed the time for ssh'ing' into the remote computer the process is cancelled.

finally, I moved on to compressing the files one by one and then tarring ( based on a suggestion that archiving consumes a lot of time for large number of files ) however, I get error that argument list is too long.

Since all these files are spread in 20 such folders, I do not want to enter each and divide into further folders and archiving & compressing it.

Any suggestions would be really helpful.

Definitely tar and gz either the whole thing or the 20 directories individually (I would do the latter to divide and conquer at least a little.) That reduces overall transfer time and provides a good error check on the other end.

Use rsync through ssh to do the transfer. If it gets hosed in the middle, use rsync --append to pick up where you left off.
