About FlashBackup
FlashBackup is a policy type that combines the speed of raw-partition backups with the ability to restore individual files. The features that distinguish FlashBackup from other raw-partition backups and standard file system backups are these:
Increases backup performance as compared to standard file-ordered backup methods. For example, a FlashBackup of a file system completes faster than other types of backup in the following case:
the file system contains a large number of files
most of the file system blocks are allocated
Enables restore of individual files from raw-partition backups.
Backs up the following file systems: VxFS (Solaris, HP, Linux, AIX), ufs (Solaris), Online JFS (HP), and NTFS (Windows).
Supports multiple data streams, to further increase the performance of raw-partition backups when multiple devices are in the list.
