About Data Transfer

Multi User relies on log files being transferred between machines. These log files form the heart of the system and ensure that synschronisation takes place.

They appear as follows:

The log file tracks every addition, change and deletion on the system and applies that to every other machine where it is relevant. Each record is uniquely identified and has a time stamp so that only the latest changes are effected on each machine.

There are 3 methods of sending these log files known as transportation methods. They use either email, FTP or direct connection over a network. When using email and FTP the file sizes being transmitted must be considered. Whilst this consideration is important, the choice of the site will override this but you should understand the implications of choosing various site types

A mirror/parent site is an exact copy of the parent site. This means that every record will be logged resulting in large log files potentially.

A single site only has records pertaining to it's site updated including any master records. This results in much smaller log files.

Customized Range is a combination of the above two sites types.

Although you can override these at run time it is advisable that you bear in mind these factors when considering what site type to choose when creating a site.
