10 About HP StorageWorks Business Copy EVA
Typical environment
In a typical environment, a management server is running HP Command View EVA and local replication
software, for example, HP StorageWorks Replication Solutions Manager.
The management server is connected by LAN to multiple hosts running replication manager host agents.
These hosts contain production database and backup applications that perform I/O on multiple storage
arrays in the SAN. An administrator or operator automates replication tasks by running jobs from a
browsing computer, a scheduler, or from a host using the replication manager command line interface.
Figure 1 Typical local replication environment
In this environment, replication manager jobs can perform simultaneous nondisruptive tape backups of the
databases. To run daily backups, for example, an administrator might create two jobs, each performing
the following steps with its respective storage array and host:
1. Momentarily suspend host application I/O to the array.
2. Make an instantaneous snapclone or snapshot of the database on the array.
3. Immediately resume host application I/O to the array.
4. Dynamically mount the snapclone or snapshot on a host for tape backup.
5. Launch a tape backup and wait for completion of the backup.
6. On completion of the backup, reverse the operations and unmount the snapclone or snapshot; then
delete it from the array and return the disk space to general use.
