This function (referred to as the disaster recovery restore function using tape media) provides a means to recover user data from operational sites to ETERNUS storage system located at disaster recovery sites, for data of the types listed below.
Backup tapes of user data stored on the ETERNUS storage system
ACM management information backed up in a package
Management information of TSM that controls tape backup operations
Point
Arrange for the following units at the disaster recovery site.
A server for data restoration (a Solaris server referred to as a tape server)
A server that uses the restored data (referred to as the storage server)
Tape unit
ETERNUS storage system
Note
The storage server arranged to process restored data must be of the same platform as the server used at the operation site.
Because the data is restored from tape media, you must restore only the TSM backup/restore environment included in ACM Tape Manager and not the entire ACM backup environment that includes processing between disks, and then restore the user data to the ETERNUS storage system according to the backup history information in the ACM management information.
