If your ADSM database or recovery log are unusable, the entire ADSM server is unavailable. Failure, damage, or loss of the database, recovery log, or storage pools can cause the unrecoverable loss of client data. If a storage pool volume is lost and cannot be recovered, any client data on the volume is also lost. This chapter describes how ADSM can guard against these situations and helps you to choose the method that is best for your installation. The term tape is used often in the following descriptions. It refers to any kind of sequential access, removable media.
See the following sections:
In this chapter, most examples illustrate how to perform tasks by using the ADSM command line interface. For information about the ADSM commands, see ADSM Administrator's Reference, or issue the HELP command from the command line of an ADSM administrative client.
All of the ADSM commands can be performed from the administrative client
web interface. A Version 3 administrative client GUI is also available
for the Windows NT and Windows 95 operating systems. For more
information about using the administrative interfaces, see ADSM Quick
Start. You can find detailed help for using the graphical user interfaces in
the online help facilities.
