5. • Unforeseen Events Happen
– Power failures
– Hardware failures – such as Servers, Switches, Hard Drives
– Human Errors!
• Huge Impacts when Mission Critical Systems are hit
– Financial, productivity, reputation, customers base/retention
• Important to Have a Plan!
• Many useful guides are available online for IT Operations

Why Disaster Recovery Planning?

6. • Modern IP-PBX systems facts:
– They are software applications running on standard computing
platforms
– They leverage the IT infrastructure: Servers, Storage, Firewalls,
Routers, Switches, LAN, WAN, etc.
– They need to be part of your DR plan!
• FreePBX (and PBXact from Sangoma) fit this model - lots of features
provided to mitigate risks

Phone Systems are Mission Critical

• Warm Spares
• High Availability Systems

FreePBX Disaster Recovery Options

9. • Local Backup
– WebGUI Driven Module
– Creates Backup of:
• Databases
• User Configuration
• Voicemail, recordings, CDRs
– Performs backup on manual or scheduled basis
– Completely customizable
• Offsite Backup (2 options)
1) You can use your own FTP Server as an external destination for offsite backups
2) Service offering automatic backup of system to Sangoma’s FTP infrastructure
This can be implemented by adding offsite backup annual license.

Backup and Restore Module
http://wiki.freepbx.org/display/FPG/Using+the+Backup+module

10. • FreePBX and PBXact run on VM infrastructure
• VM Snapshot is a great feature
– A copy of the virtual machine's disk data, configuration, disk file at a particular
point in time
– To restore a VM to that particular point in time
• VM Snapshot vs Backup &restore
- VM snapshot
• Restores a complete system (including OS and all data and configuration)
- Backup & Restore
• Restores only FreePBX user configuration/data/Voicemail on an exiting FreePBX VM system
- Restoring from a VM snapshot is faster than restoring a backup

Virtual Machine Snapshot

11. Warm Spare
11
• Two FreePBX / PBXact server setup
• Warm spare will keep a backup of primary system
– This is pre-configured upon setup, and optionally
scheduled
• Failover is Manual
• When failure occur
– Disconnect production server from network
– Change IP address of warm spare system to the
production server IP address
• No special licensing required for Warm Spare
– Must have individual Deployment IDs per server
– Commercial Module Licenses must be identical on both
boxes

SIP phones, Gateways, SBCs are automatically directed to an
active server. No technician intervention required on these

12. High Availability (HA) Add-On
12
• HA License
– Two FreePBX / PBXACT servers setup in a High
Availability configuration
– Configuration is synchronized between two
units
– Constant monitoring
– If Primary server fails the other automatically
takes over
• Failover time ~ < 1 minute
• 1 HA license per server is required
• Commercial Module Licenses must be
identical on both boxes
