After IBM Storage Protect Snapshot for
Windows is registered to IBM Storage Protect, you must configure the node name, password, the
communications method, and the appropriate parameters to connect to the IBM Storage Protect
server.
Before you begin
When you manually set configuration parameters for IBM Storage Protect,
ensure that the IBM Storage Protect Snapshot options file (dsm.opt) and the backup-archive client
options file (also dsm.opt) specify the same IBM Storage Protect server.
About this
task
You can use the configuration wizard to set the configuration parameters. To
manually configure the parameters, complete the following steps.
Procedure
- If you are running IBM Storage Protect
Snapshot on a Microsoft Windows Failover Clustering or Veritas Cluster Server, ensure that the
options files on each cluster node are identical by editing the options file. Use a text editor to
edit the file.
The dsm.optoptions file
includes the following parameters, which are necessary for initial configuration:
- COMMMethod
- Specify the communication protocol to
use between the IBM Storage Protect Snapshot node and the IBM Storage Protect server. Depending on
the commmethod option that you choose, specify one of the following connectivity parameters for the
commmethod values.
- For VSS backups, specify the COMMMethod option in the IBM Storage
Protect Snapshot options file.
- For VSS backups, specify the COMMMethod option in the
backup-archive client options file that is used as the Local DSMAGENT Node. If the environment is
configured for VSS offloaded backups, you must also specify the COMMMethod option in the
backup-archive client options file that is used as the Remote DSMAGENT
Node.
- NODename
- Specify the IBM Storage Protect node name that IBM Storage Protect uses to
identify the system that runs IBM Storage Protect Snapshot.
- PASSWORDAccess
- Specify either the default
generate value to generate a password automatically, or specify the
prompt password to respond to a request for a
password.
- Optional: modify the
default values for the following parameters:
- CLUSTERnode
- In the DSMAGENT options files, specify the CLUSTERnode option and set it to no. For the IBM
Storage Protect Snapshot options file, specify the CLUSTERnode option and set it to
yes.
- HTTPport
- Specify
the HTTP port. The default value is
1581. - TCPPort
- Specify the TCP port.
- TCPServeraddress
- Specify the TCP server
address.
- CLUSTERSHAREDFOLDER
- In the IBM Storage Protect Snapshot for SQL Server options file
(tdpsql\dsm.opt), specify the directory location in which to store encrypted password files. Specify
a location that all nodes in the cluster can access. If a failover occurs, the backup-archive client
uses this option to determine where the password files are
located.
- Optional: For VSS backups
that are sent to the IBM Storage Protect server, specify the following options to enable features
for the data that is sent to the IBM Storage Protect server.
When you use these options, you must update the backup-archive client options file
that is used as the local DSMAGENT node and the remote DSMAGENT node.
- COMPRESSIon
Specify the
compression
yes
option if any of the following conditions exist:
- The network adapter has a data overload
- Communications between IBM Storage Protect
Snapshot and IBM Storage Protect server are over a low-bandwidth connection
- Heavy network
traffic exists
Specify the
compression
no
option if any of the following conditions exist:
- The computer that runs IBM Storage Protect Snapshot has a processor overload; the added
processor usage might cause issues for other applications that include the server. You can monitor
processor and network resource usage with the Performance Monitor program that is included with
Windows.
- You are not constrained by network bandwidth; you can achieve the best performance
by leaving the
compression no option unchanged and enabling
hardware compaction on the tape drive, which also reduces storage
requirements.
For VSS backups, specify the COMPRESSIon option in the
backup-archive client options file that is used as the local DSMAGENT node. If the environment is
configured for VSS offloaded backups, specify the COMPRESSIon option in the backup-archive client
options file that is used as the remote DSMAGENT node.
If you
are running offloaded backups, a dedicated (and unique) remote DSM agent node must exist for each
local DSM agent node.
- DEDUPLication
Specify whether the IBM Storage Protect API deduplicates data before the
data is sent to the IBM Storage Protect server. Specify Yes or No. The value applies only if IBM
Storage Protect allows client-side data deduplication.
When you specify both deduplication
and ENABLELANFree options, the deduplication option is ignored.
You can enable client-side
data deduplication by specifying DEDUPLICATION YES in the dsm.opt
file.
- ENABLELANFree
- If you run data backup and restore operations in a LAN-free environment,
specify ENABLELANFree yes in the DSMAGENT (VSS Requestor) options file.
- ENABLECLIENTENCRYPTKEY
- Specify this option to
encrypt databases during backup and restore processing by generating one random encryption key per
session.
Restriction: You can back up encrypted VSS databases
only to the IBM Storage Protect server. You cannot back up encrypted data to an IBM Storage
Protect Snapshot server.
You can specify DES56 (56 bit), AES128 (128 bit), or AES256 (256
bit). The most secure data encryption method is AES256.
In the options file, you must also
specify the databases that you want to encrypt by adding an include statement with the
include.encrypt option.
For VSS backups, specify the encryption options in the backup-archive
client options file that is used as the local DSMAGENT node. If the environment is configured for
VSS offloaded backups, specify the encryption options in the backup-archive client options file that
is used as the remote DSMAGENT node.
If you make changes in the backup-archive client options
file, ensure that you restart the IBM Storage Protect Client Acceptor Daemon (CAD) service for the
Exchange or SQL Server.
What to do next
You can create
more IBM Storage Protect Snapshot for Microsoft Exchange Server or IBM Storage Protect Snapshot
for Microsoft SQL Server options files to point to another IBM Storage Protect server. You can
create more than one options file, where each file contains different parameters to use with a
single IBM Storage Protect server.
