The SynergyVSSWriter service coordinates between an operating system backup provider and the synbackup utility to prevent corruption of the files being backed up.
Stop the SynergyVSSWriter service.
Register the SynergyVSSWriter service.
Register the SynergyVSSWriter service (if necessary) and then start it.
Unregister (remove) the SynergyVSSWriter service. If the service is running, -x will first stop it.
The purpose of the SynergyVSSWriter service is to automatically turn synbackup on while a system backup is in progress and turn it off when the backup is finished. Synbackup ensures that ISAM files are synchronized correctly.
The default path where SynergyVSSWriter will watch for Volume Shadow Copy Service (VSS) events to occur is C:\ and the file specification to match is *.is*, or you can designate the path and filename specification using the SYN_VSS_WATCH_PATH and SYN_VSS_WATCH_FILE environment variables. If you manually or automatically trigger a file backup in the designated path with the designated file specification, SynergyVSSWriter will be invoked and given the opportunity to run synbackup before letting the backup operation be carried out. Once the backup operation is completed, synbackup will be turned off again.
SynergyVSSWriter works with any VSS provider that supports SQL server backups.
