How much data do you want to back up?
When calculating the total amount of data to be backed up consider the current requirements and the expected growth in the data in the near future. Table: Calculating the amount of data to be backed up lists the considerations to be made for calculating the amount of data to be backed up.

Checks to calculate the amount of data to be backed up | Additional comments |
---|---|
Have you computed the total disk space on each individual system? |
|
Have you identified and added all the data types included in the backup? | Ensure that you have identified and listed all the data types to be included in the backup. For example, does the data contain text, graphics, databases, and so on. Each data type contributes to a specific amount of data in your total backup requirement. Some of the advantage of identifying the data types to be backed up are listed below:
|
How compressible is the data? | Identify how much amount of data from your total capacity is compressible or not. Based on this information you can ascertain the amount of space to be allocated to backup data that is compressible and to data that is incompressible. |
Will the data be encrypted? | Identify if you want to encrypt the data during backup. Based on the level of security applicable to the data being backed up this decision can be taken. Note: You will also need to consider the additional time encrypted backups may take. Based on which your backup schedules will get affected. |
Have you added the space on mirrored disks only once? | Ensure that you consider the amount of data stored on these repositories only once, if you use storage replication or disk mirroring techniques. |
Have you added the size of your database backups to your final calculations? | Ensure that you add the amount of data stored on all the database management systems maintained in your organization. |
What are your data protection requirements? | Understand the data protection requirement for the data to be backed up, like the SLA, disaster recovery, and Backup retention and so on. |
Have you added the requirements of the test-backup environment? | Create an independent test-backup environment to ensure that your production environment will work with the changed backup solutions. The test-backup environment helps to keep in study the effects of a new backup solution and of the changes made to the hardware and the software infrastructure over a period of time |
Have you added any resulting growth factor to your total backup solution? | Identify the annual data growth factor to calculate capacity increase over years. |
Have you computed the amount of data you will need to backup in the next six months to a few years from now? | Ensure that you have computed the growth in amount of data in the next six months to a few years. Based on the expected growth you can identify the strategy to expand your existing storage configurations, as required. |
