Once a job is selected to be retained, the status for that job is displayed as Available and Retained in the Status column. Once selected, this job will not be pruned when a data aging operation is run. Once retained, the job can be de-selected for manual retention using the Do Not Retain Job Option.

When viewing jobs on this copy, no jobs will be visible on this copy until the Show all option is enabled. * * 注意：保留中的保留天数和周期的关系： 备份周期可以由用户定义，但CV会以全备份为分界点自动判别。1个备份周期包含了1个全备份和与之相关的增量或差异备份。 这2个选项是或的关系， 举例： 如果用户定义的备份周期为3天的备份循环，那么该备份数据将保留15天。（因为 3天 x 2 ＝6 天 15天） 如果用户定义的备份周期为1周的备份循环，那么该备份数据将保留15天。（因为 7天 x 2 ＝14 天 15天） 如果用户定义的备份周期为2周的备份循环，那么该备份数据将保留28天。（因为14天 x 2 ＝28天 15天） * 注意：保留中的保留天数和周期的关系： 备份周期可以由用户定义，但CV会以全备份为分界点自动判别。1个备份周期包含了1个全备份和与之相关的增量或差异备份。 这2个选项是或的关系， 举例： 如果用户定义的备份周期为3天的备份循环，那么该备份数据将保留15天。（因为 3天 x 2 ＝6 天 15天） 如果用户定义的备份周期为1周的备份循环，那么该备份数据将保留15天。（因为 7天 x 2 ＝14 天 15天） 如果用户定义的备份周期为2周的备份循环，那么该备份数据将保留28天。（因为14天 x 2 ＝28天 15天） * * Clients are tracked for licensing and control by client name. The fully qualified domain name defines the TCP/IP path used to manage the iDataAgents on the clients. Each client has one or more iDataAgents. An iDataAgent can only be installed if the associated data/application is present. i.e. you cannot install an Exchange 2000 Database iDataAgent on a host that is not running and Exchange 2000 instance.
