- We do our backups by mounting the OS/2 drives on a SCO UNIX machine
- and running TAR under UNIX. We found that we had to reduce the buffer
- sizes to 1024 bytes before it would work. We didn't need to go as low
- as 512 bytes. It's not quick though. We are hoping to use an OS/2
- TAR with IBM TCP/IP's rexec or rsh as a better method for the backups.
