Define the periods of time during which backups of specific systems can be
done.
• Local versus network backups
Determine which systems, that the backup devices are connected to, are
backed up locally and which are backed up over the network.
• Backup policy implementation
• How backups are done, and which backup options are used
This defines the frequency of full and incremental backups. It also defines the
backup options that are used, and whether the backups are permanently
protected with the backup media stored at a remote site.
• How the systems are grouped into backup specifications
Consider how best to group backup specifications. This can be on the basis
of departments, data types, or backup frequency.
• How the backups are scheduled
Consider using the staggered approach, whereby full backups are scheduled
for different clients (backup specifications) on different days to avoid network
load, device load, and time window issues.
• Retaining data on media and information about backups
Consider protecting data from being overwritten by newer backups for a
specified amount of time.
Define the period of time that the Data Protector Catalog Database should
store information about backups.
• Device configuration
Determine the devices to be used for backups and the systems they are connected
to. Connect the backup devices to systems with the greatest amount of data so
that as much data as possible is backed up locally and not through the network.
This increases backup speed.
If you have large amounts of data to back up, consider using a library device
• Media management
Determine the type of media to be used, how to group the media into media
pools, and how to position objects on the media.
• Vaulting
Decide whether to store media to a safe place, where it is kept for a specific
period of time.
• Backup administrators and operators
