[rdiff-backup-users] rdiff-backup compatibility with older versions?

[abhi]

Hello,

I have a Linux box running rdiff-backup 0.12.7 and a Solarix box w/ 0.13.4.
Attempting to pull data from Linux onto Solaris fails (and so does other way
round too). --test-server returns warning but says "may work":

solaris# rdiff-backup --test-server address@hidden::/home .
Warning: Local version 0.13.4 does not match remote version 0.12.7.
Testing server started by:  ssh -C address@hidden rdiff-backup --server
Server may work, but there is a version mismatch:
Local version: 0.13.4
Remote version: 0.12.7

But doing an actual backup, I get "Truncated header string.." error :(

solaris# rdiff-backup  address@hidden::/home/user .
Warning: Local version 0.13.4 does not match remote version 0.12.7.

--------------------------------

Firstly does this combination of version numbers designed to work together?

If yes, any idea what might be going wrong? if anyone needs more info (e.g.
          output with -v9) let me know.

If no, why? I thought as long as we are at same/compatible level of 
        librsync (>= 0.9.6) things should work. no?

Thanks
