Command Line Configuration - UNIX/Linux File Systems

Log On to the CommServe

To run command line operations, you must first login to the CommServe.

From Command prompt, navigate to <Software_Installation_Directory>/Base and run the following command:

 
qlogin -cs <commserve name> -u <user name>

For example, to log on to CommServe 'server1' with username 'user1':

qlogin -cs server1 -u user1

Backup Set Configuration

Use the following qcommands to configure backup sets for the Unix File System iDataAgent:

qcreate backupset
Description

This command creates a new backup set under the given client and agent.

The qcreate backupset command also allows the user to create default backup sets and on-demand backup sets. The default subclient created under the backup set can also be associated with a storage policy. If a storage policy name is not included, the subclient remains unassigned.

Upon successful completion, qcreate backupset displays the message "Created backupset successfully" on the command prompt. In case of an error, an error code and description are displayed as: "backupset: Error errorcode: errordescription"

Usage
qcreate backupset -c client -a dataagenttype -i instance -n backupset [-sp storagepolicy] [-t NORMAL|DEFAULT|ONDEMAND] [-tf tokenfile] [-tk token] [-af Argument Filepath] [-h]

qdelete backupset
Description

This command deletes a given backup set.

When the backup set to be deleted contains archived data, the command asks the user to confirm the deletion. This prevents the user from accidentally removing backup sets that may have archive jobs. If you want to skip the confirmation prompt, you can use the "-skc" option.

Upon successful completion, the qdelete backupset command displays the message "Deleted backupset successfully" on the command prompt. In case of an error, an error code and description are displayed as: "backupset: Error errorcode: errordescription"

-a

Agent type installed on client computer (see Argument Values - Agent Types)

-b

Name of the backup set to be deleted

-skc

Skips the confirmation prompt to delete the backup set if archived data is found on the backup set.
