Re: Split a Replica Job Into Two

Thank you for your reply Greg.

OS is Ubuntu Linux 20.04.6.
Version of Unison is 2.40.102
File system type is ext4

Servers are separated with different Internet connections and they 
replicate through ssh.  I have a cron script that calls the command every 
five minutes so they will replicate any changes in a timely manner.

As noted, haven't had any issue with the archive files getting corrupt for 
years.. unless a server lost power during a replication process.  But in 
the last two months, I've had corrupt archive files at least four times now.

Today's archive error was:

Fatal error: Server: Corrupted archive: the files <FILE1> and <FILE2> are 
not correctely ordered in directory <PATH>

I changed the filenames and the path.

Since all of the home folders are in the "/home" path, that entire path is 
replicated with some folder exceptions.

Like you said, big change if I cannot just replicate the /home folder.  I'd 
need to make sub-folders in the home.. such as an "a-j" and "k-z" and then 
place the home folders in there.  But that would be a great deal of 
re-configuration.
