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
![Page 5: Safe data, strong future: safeguarding your business and data from disaster](https://reader033.fdocuments.net/reader033/viewer/2022052819/5455d73bb1af9fb66e8b4b1a/html5/thumbnails/5.jpg)
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
![Page 6: Safe data, strong future: safeguarding your business and data from disaster](https://reader033.fdocuments.net/reader033/viewer/2022052819/5455d73bb1af9fb66e8b4b1a/html5/thumbnails/6.jpg)
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
![Page 7: Safe data, strong future: safeguarding your business and data from disaster](https://reader033.fdocuments.net/reader033/viewer/2022052819/5455d73bb1af9fb66e8b4b1a/html5/thumbnails/7.jpg)
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?
![Page 8: Safe data, strong future: safeguarding your business and data from disaster](https://reader033.fdocuments.net/reader033/viewer/2022052819/5455d73bb1af9fb66e8b4b1a/html5/thumbnails/8.jpg)
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?
![Page 9: Safe data, strong future: safeguarding your business and data from disaster](https://reader033.fdocuments.net/reader033/viewer/2022052819/5455d73bb1af9fb66e8b4b1a/html5/thumbnails/9.jpg)
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
![Page 10: Safe data, strong future: safeguarding your business and data from disaster](https://reader033.fdocuments.net/reader033/viewer/2022052819/5455d73bb1af9fb66e8b4b1a/html5/thumbnails/10.jpg)
The setup
• Stand-alone server• 4 year old equipment• Email services• Application database
![Page 11: Safe data, strong future: safeguarding your business and data from disaster](https://reader033.fdocuments.net/reader033/viewer/2022052819/5455d73bb1af9fb66e8b4b1a/html5/thumbnails/11.jpg)
BASIC backup strategy
• Utilize built-in tools– Advantages
• Easy to use• Inexpensive
– Limitations• Not compatible with all backup media• Not database aware
![Page 12: Safe data, strong future: safeguarding your business and data from disaster](https://reader033.fdocuments.net/reader033/viewer/2022052819/5455d73bb1af9fb66e8b4b1a/html5/thumbnails/12.jpg)
BETTER backup strategy
• Third-party software– Advantages
• Automates complex backup procedures• Database aware
– Limitations• Costs for configuration and maintenance• Must manually move media offsite
![Page 13: Safe data, strong future: safeguarding your business and data from disaster](https://reader033.fdocuments.net/reader033/viewer/2022052819/5455d73bb1af9fb66e8b4b1a/html5/thumbnails/13.jpg)
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
![Page 14: Safe data, strong future: safeguarding your business and data from disaster](https://reader033.fdocuments.net/reader033/viewer/2022052819/5455d73bb1af9fb66e8b4b1a/html5/thumbnails/14.jpg)
BEST backup strategy
• Onsite backup to disk with offsite replication– Advantages
• Fast backup and recovery• Small backup window
– Limitations• Initial costs• Recurring fees
![Page 15: Safe data, strong future: safeguarding your business and data from disaster](https://reader033.fdocuments.net/reader033/viewer/2022052819/5455d73bb1af9fb66e8b4b1a/html5/thumbnails/15.jpg)
Replication strategy
![Page 16: Safe data, strong future: safeguarding your business and data from disaster](https://reader033.fdocuments.net/reader033/viewer/2022052819/5455d73bb1af9fb66e8b4b1a/html5/thumbnails/16.jpg)
Demo
• Backup• Restore• Virtualization
![Page 17: Safe data, strong future: safeguarding your business and data from disaster](https://reader033.fdocuments.net/reader033/viewer/2022052819/5455d73bb1af9fb66e8b4b1a/html5/thumbnails/17.jpg)
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?
![Page 18: Safe data, strong future: safeguarding your business and data from disaster](https://reader033.fdocuments.net/reader033/viewer/2022052819/5455d73bb1af9fb66e8b4b1a/html5/thumbnails/18.jpg)
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
