Tape-Based Protection Process

更新日期: 2010年4月

適用於: System Center Data Protection Manager 2010

When you use short-term disk-based protection and long-term tape-based protection, DPM can back up data from the replica volume to tape so that there is no impact on the protected computer. When you use tape-based protection only, DPM backs up the data directly from the protected computer to tape.

DPM protects data on tape through a combination of full and incremental backups from either the protected data source (for short-term protection on tape or for long-term protection on tape when DPM does not protect the data on disk) or from the DPM replica (for long-term protection on tape when short-term protection is on disk).

note附註
If a file was open when the replica was last synchronized, the backup of that file from the replica will be in a crash consistent state. A crash consistent state of the file will contain all data of the file that was persisted to disk at the time of last synchronization. This applies only to file system backups. Application backups will always be consistent with the application state.

For specific backup types and schedules, see Planning Protection Groups.
