“It is only when they go wrong that machines remind you how powerful they are.”
Clive James
On planning …
Backup and recovery definitions
• Backup– The process of copying data so that any lost or corrupt
data can be recovered• Backup window
– Time slot when the backup can run without interrupting access to the data
• Storage media– Physical storage device that holds the backup data
Backup and recovery definitions
• Recovery window– Amount of time between the failure and recovery when
users cannot access data and applications• Bare metal restore
– Ability to restore data to hardware that is different from the original
• Deduplication (aka “single instance storage”)– Reduce storage requirements by eliminating duplicated
data
Backup and recovery definitions
• Backup types– Full
• Entire system is backed up– Incremental / differential
• Effects only files that changed since last backup
• Open file backup– Software that allows locked files to be backed up
• Server virtualization
Before you start, a few questions
• What do I need to backup?• How often do I need to run the backup?• Who will be responsible for changing the media and
verifying the backup was successful?• What is the size of my backup?
Before you start, a few more questions
• How long can my company be productive without access to this data?
• What do I need to protect my company from?• How do I keep the backup data secure?• What are my compliance issues?
Recommended minimums
• Backup media should be 1.5 to 2 times the size of your current backup data set
• Every two weeks – full backup rotation• Quarterly – restore testing of random data from
current backup• Daily backup kept in fire and waterproof safe
The setup
• Stand-alone server• 4 year old equipment• Email services• Application database
BASIC backup strategy
• Utilize built-in tools– Advantages
• Easy to use• Inexpensive
– Limitations• Not compatible with all backup media• Not database aware
BETTER backup strategy
• Third-party software– Advantages
• Automates complex backup procedures• Database aware
– Limitations• Costs for configuration and maintenance• Must manually move media offsite
BETTER backup strategy part II
• Backup directly to offsite location or service– Advantages
• Automated process• Database aware
– Limitations• Slow backup and recovery• Not suitable to high transaction environment
BEST backup strategy
• Onsite backup to disk with offsite replication– Advantages
• Fast backup and recovery• Small backup window
– Limitations• Initial costs• Recurring fees
Replication strategy
Demo
• Backup• Restore• Virtualization
Testing
• How important is it that your data is available in the event of a failure?
• When do you want to find out there is a problem with the backup media?
Benefits
• Having a backup of your most critical data will allow you to recover in case of emergency
• Having an automated backup strategy reduces errors• Having a disk backup solution provides incredible
speed and reliability• Replicating offsite keeps your data more accessible in
the event of a catastrophic failure• Virtualization provides an extremely fast and flexible
set of options for getting your business operational
