Synchronization will not work if there is no backup file or if there is a backup in
progress.
On the standby server, during either scheduled or on-demand synchronization, the
standby server pulls the current backup from /usr/local/smx/backups
on the primary server.
NEVER schedule a synchronization or perform an on-demand synchronization at the same
time a backup is occurring on the primary server.
NEVER start an on-demand backup while synchronizing servers.
The backup file is copied to /usr/local/smx/backups on the standby
machine which brings up two important points:
NEVER schedule a local, remote or on-demand backup on the standby machine.
If you do, it will overwrite the file transferred over from the primary
server.
NEVER direct a backup from the primary server to
/usr/local/smx/backups on a standby server. This will
prevent synchronization from working properly.
NEVER back up to the desktop from the standby server, because that process
overwrites the existing file in /usr/local/smx/backups.
As the second part of synchronization, the standby server runs a restore to itself
using the file found in its own /usr/local/smx/backups directory.
This should be the only file ever copied over from the primary server.
