One of the problems with a shared data set is making sure it is backed up correctly. Most backup software cannot backup open files, so to be sure everything is secure the database server needs to be stopped so all the files get closed, then a backup needs to be taken, then the database server needs to be restarted.
The MailCOPA Email Client V12 will contain a live backup system. It can synchronise a backup to occur at any time during the day, and it will backup file that are not only open, but are actually in use. By reading the data at database level a secure backup of the files can be copied to another location on disk. These files remain closed allowing normal 3rd party backup software to safely back those up to an off-site location.
It's expected that V12 of the MailCOPA email client will be released in the next 2-3 months. For more information see the MailCOPA email client web pages.
