Considerations for scheduling backups

Planning schedules for backups in an environment requires careful consideration of several factors.

For example:

  • The amount of data you must back up.
  • The number of backup media volumes to use.
  • The amount of time available to complete a backup.
  • The number of volumes that are required to recover from a disaster such as a disk failure.

Recovery considerations

You must also determine the requirements for recovering files. For example, if users expect to recover any version of a lost file that was backed up during a three-month period (that is, the retention setting is three months), then you must maintain all the backup volumes for a three-month period. However, if users expect to be able to recover data from only the last month, you do not need to maintain as many volumes.
