Backup
Pre- and Post-Exec Commands
Chapter 5
262
✓ The
pre-
and
post-exec
processes operate in background mode.
Therefore, do not use any interactive commands for the
pre-
and
post-exec
processing.
✓ If a command writes any text to
stdout
, this text is received by the
Disk Agent, sent to the Session Manager, and written to the
database. A
stderr
is redirected to
/dev/null
. You can redirect it to
stdout
to get error messages logged to the database.
✓ The
pre-
and
post-exec
commands for an object have to be located
on the client where the Disk Agent is running.
✓ The
pre-
and
post-exec
commands must be executable and specified
with the full pathname.
✓ You can disable
pre-
and
post-exec
scripts by adding the line
OB2OEXECOFF=1
into the
omnirc
file on any client.
✓ You can secure the client by specifying which Cell Managers are
allowed to access the client. Only permitted Cell Managers will be
able to execute
pre-
and
post-exec
commands on the client. For
more information on securing a client, refer to the HP OpenView
Storage Data Protector Installation and Licensing Guide.
