Backup Withholding Period
Backup withholding period defines how much history of your backups you keep before
you run them over with a new backup.
Sometimes, if not always, it take time to notice a problem!
A very short backup withholding
period will not give you enough time to notice problems that take a while to
discover, and will leave you with useless backups that all have the problem
duplicated.
For the majority of the organizations it is enough to have a backup withholding
period that is long enough to make it possible for them to recognize the problem
before all of the backup generations are infected with the problem. Others may want to withhold their backups for longer periods to comply
with statutory regulations. For example a firm needs to keep the Account
Receivable records for a period of 3-5 years.
As RRB keeps only the incremental change from one generation to the other,
increasing the withholding period consumes a space that can be 20-60 times
smaller than other solutions.
