Differences between Backup on Appliance Product Families
The backup feature functions similarly on all LogLogic appliance product families.
The only significant difference comes in the amount of disk space taken by different types of backed up data:
| Appliance Product Family | Configuration Database | Real Time Database | Raw Log Files |
|---|---|---|---|
| LogLogic LX Appliance, LogLogic MX Appliance | Similar | Larger | Similar |
| LogLogic ST Appliance | Similar | Very small | Similar |
Performance Metric
The following equation calculates the minimum time required for a backup or restore:
data-size / network-speed = minimum-time
data-size is the total size (in MB) to backup or restore
network-speed is the network speed (in MB/second)
minimum-time is the least possible time the process takes (in seconds)
For example, the minimum time needed to back up or restore 10,000 MB (10 GB) data through a 100 Mb (12.5 MB/sec) network is:
10,000 / 12.5 = 800 sec = 13 min 20 sec
Performance beyond this minimum time depends on many factors, including network bandwidth, and processor speed and availability.
It is good practice to use a 1 GB interface to provide a higher network bandwidth.
