The amount of time it takes to back up or restore data depends on various factors. These factors include:

• Amount of data: An increase in the amount of data causes an increase in the amount of time it takes to back up or restore the data. Some factors that increase the amount of data being stored are:

  • Number of items being measured: More data is generated if you measure 100,000 agent skill pairs instead of 10,000.

  • Number of days information is stored: The greater the data storage time, the greater the amount of data to be backed up or restored. When CMS reaches the threshold for data storage, the system deletes the oldest record to accommodate the newest record. You can store the data for 370 days.

  • Interval size: Shorter intervals generate more data. A 15-minute interval generates significantly more data than a 60-minute interval.

• System load: Processes that require a large number of system resources slow down the CMS system. Backing up data requires a large amount of system resources. Additional processes that require a large amount of system resources are:

  • Running reports: Running a single large report or multiple smaller reports uses a large amount of system resources.

  • Archiving data: Archiving a large amount of data uses a large amount of system resources.

• The device you are backing up to can also affect the time the backup takes. For the latest CMS releases, you should be using a network mount point for backups. Consider a backup strategy such as the following:

  • Perform full backups only once a week.

  • Perform incremental backups every other day, three or four times a week.

    For example, you might want to perform your full backup on Saturday nights, and your incremental backups on Mondays, Wednesdays, and Fridays.
