Solution #00004477
Scope:
Applies to all Barracuda Backup Servers using Barracuda
Backup Agent to capture MS Exchange or MS SQL database.
Answer:
The Smart backup feature is a tool used to minimize impact of database backups
on network resources necessary to transfer data off site.
It is available through the Web Interface under Backup Tab > Schedules > Agent Details. Selecting the Backup
Type Smart and setting the Minimum Threshold and Maximum Threshold will give the Backup
Server a set of rules for switching between full and transaction log
(incremental) database backups.
Minimum Threshold sets the floor. A full backup will be performed no more
frequently than the number of days selected. The default is seven days.
Maximum Threshold sets the ceiling. A Full backup will be performed no less
frequently than the number of days selected. The default is 14 days.
After a number of days equal to the Minimum Threshold the Backup Server will
begin checking how much data is on the Offsite Transfer Queue each time a
backup run is scheduled. If there is more than 1 GB on the queue, the Backup
Server will perform a log backup. It will continue to check each successive backup
run until there is either less than 1 GB on the Offsite Transfer Queue or until
the Maximum Threshold is reached.
If the Backup Server gets to the Maximum Threshold, a full database backup will
run no matter the status of data on the Offsite Transfer Queue.
