Configurable Options
Options are used to optimize and customize the operation of the client agent. However, none of these options are required for the client agent to run. A complete list of options are available for use when starting the UNIX, Linux, or Mac OS X client agents as shown in the following table.
Note: These options should be carefully set by administrators having UNIX, Linux, or Mac OS X knowledge. If you do not understand what an option or parameter means, do not set the feature unless instructed to do so by a Arcserve Technical Support representative.
|
Option |
Description |
|---|---|
|
-ALLOW |
Use this option with Single User mode, with the -S or -NOPASSWORD option, to define the IP addresses of computers that are authorized to access the client agents without requiring validation. |
-ALLOW N:172.16.0.0(255.255.255.0) H:172.31.255.255
In this example, N denotes a network address and H denotes a host IP address. You can set an optional subnet mask.
|
Option |
Description |
|---|---|
|
-b bufsize |
Defines the disk I/O buffer size in bytes. Options are 16384 to 65536 bytes; the default is 65536 bytes. |
|
-c n |
Specifies the sleep time while waiting, in milliseconds (ms). Options are zero (0) to 1000 ms; the default is 50 ms. |
|
-CAUSER USER |
Defines Single User mode. Used with the -S or NOPASSWORD option to set the Allow or Deny list on a per-user basis. |
For example:
-CAUSER A: USER1 N: USER2
In this example, A means –ALLOW and N corresponds to -DENY.
|
Option |
Description |
|---|---|
|
-DENY |
Use this option with Single User mode, with the -S or NOPASSWORD option, to define the IP addresses that are not allowed access to the client agents. |
For example:
-DENY N:172.16.0.0(255.255.255.0) H:172.31.255.255
In this example, N denotes a network address and H denotes a host’s IP address. You can set an optional subnet mask.
|
Option |
Description |
|---|---|
|
-l |
Causes the client agent to check for advisory locks. The default is mandatory locks only. |
|
-m maxbuf |
Sets the number of buffers allocated for I/O. Options are 2 to 1024 buffers; the default is 128. |
|
-NOPASSWORD |
Specify this option if you need to use either the -ALLOW, -DENY, or -CAUSER options. This option is the same as the -S option in Single User mode with no password required. |
|
-P n |
Specifies the default time out, followed by a variable number (n), which is user-defined and measured in minutes (0 to 10). The default is 5 minutes. |
For example, the option -P 10 assigns a wait time period for the backup or restore pre-script of 10 minutes.
Note: An error occurs if you use the -P option without defining a number n.
|
Option |
Description |
|---|---|
|
-Prebackup -Postbackup -Prerestore -Postrestore filename |
Executes the default pre-scripts and post-scripts associated with the type of backup or restore job being run. The filename is optional and if is not specified, uag_pre_backup will be treated as the filename. |
|
-S |
Enables the Single User mode option. In Single User mode, user credentials are not checked against valid user IDs and passwords. Instead, access is granted based on the -ALLOW, -DENY, or -CAUSER options. For more information see the specific option. |
|
-s async| |
Sets socket I/O to asynchronous, nonblocking mode. |
|
-s bufsize |
Specifies the size of the socket buffer. Options are 4096 to 65536. The default is system dependent. |
|
-s SocketMode |
Specifies to use socket mode for backup operations. |
|
-sparse |
Differentiates between sparse file and regular file operations.This option increases the efficiency of sparse file backups and restores. Note: Quota files are always treated as sparse files in backup and restore operations, regardless of whether you specify –sparse. |
|
-verbose or -v |
Places the system in verbose mode to enable the entry of detailed debugging messages at the console. |
