Designate one machine as the primary machine. This machine will store the primary copy of the snapshot database.

Every so often, copy all newly created snapshot records from each of the non-primary machines to the primary machine. (As long as the snapshot database has not been sorted on the non-primary machines, all newly added records are at the end of the database). The newly added records can be extracted via main menu option Snapshot followed by Export records. Export all records outside the sorted region (this is the default) into an output file. Copy this output file onto the primary machine. On the primary machine, use Snapshot followed by the import records function to import the output file into the snapshot database. After importing records onto the primary machine, sort the database on the non-primary machine. Every so often, sort the database on the primary machine, break it up into pieces and/or zip it up and replace the snapshot databases on each of the non-primary machines.

I usually copy records from my non-primary machines to my primary machine after I’ve entered 300 records or so. I usually replace the snapshot database on my non-primary machines every 3 months or so.

Note: Editing a snapshot record (as opposed to creating a new snapshot record) does not add a record to the database, and hence the above mentioned procedure will not copy this change onto the primary machine. The only way to get these changes is to manually edit the same record on the primary machine. Hence, if you tweak a facing direction or active attribute of a snapshot record within the sorted region of a non-primary machine, write yourself a note so that the same change can be made later on the primary machine.

A similar procedure can be followed with the getin/getout databases.
