Performing Incremental Backup

In this article

    To perform incremental backup, Veeam Agent for IBM AIX uses the tar utility. To work with the utility, Veeam Agent for IBM AIX uses the veeam_backup script. The veeam_backup script is a UNIX shell script that instructs tar to work with backup locations configured in Veeam Agent for IBM AIX and create backup files according to the naming conventions defined in the product.

    Before you perform incremental backup, make sure that the necessary backup location (that is, the backup location intended for keeping backup files of the machine whose data you back up) is selected as the default backup location. To learn more, see Specifying Default Backup Location.

    To perform incremental backup, use the following command.

    veeam_backup [-v] [-R <value>] <path/to/directory>

    where:

    • -v — option that enables the verbose output (disabled by default).
    • -R <value> — option that defines the number of backup files to keep in the backup chain (the default value is 720).
    • <path/to/directory> — path to the directory that you want to back up. You can specify a path to the root directory in the file system of your machine (/) to create backup of the entire system image. Alternatively, you can specify a path to a specific directory that contains data that you want to back up.

    Examples

    The following example displays a command to create an incremental backup of the entire system image. Veeam Agent for IBM AIX is set up to keep 14 incremental backup files in the target location.

    veeam_backup -R 14 /

     

    The following example displays a command to create an incremental backup of the directory that contains Veeam Agent for IBM AIX log files. The verbose output is enabled for the incremental backup process.

    veeam_backup -v /var/log/veeam
