It is important to plan the Snapshot copy transfer schedule and retention for your SnapVault backups.
When planning SnapVault relationships, consider the following guidelines:
Does the data change often enough throughout the day to make it worthwhile to replicate a Snapshot copy every hour, every two hours, or every four hours?
Do you want to replicate a Snapshot copy every night or just workday nights?
How many weekly Snapshot copies is it useful to keep in the SnapVault secondary volume?
