Using Arcserve UDP Agent (Linux) › How to Back up Linux Nodes › Configure the Backup Settings and Run Backup Job › Specify the Backup Source

Specify the Backup Source

Specify the backup source nodes in the Backup Wizard so that you can back up those nodes to a desired location. The Backup Source page of the Backup Wizard displays the node that you want to backup. Use the Add button on this page to add more nodes for backup.

Note: If you open the Backup Wizard using the Back Up Selected Nodes button, then all the selected nodes are listed in the wizard page. If you open the Backup Wizard using the Back Up button, then nodes are not listed in the wizard page. You have to add nodes using the Add button in the wizard page.

Follow these steps:

1. Select the nodes that you want to back up from the Nodes tab.
2. Click Backup, and select the Back Up Selected Nodes option from the Wizard menu.

   The Backup Server page of the Backup Wizard opens. The Backup Server page displays the server name.

3. Click Next.

   The Backup Source page opens. The previously selected nodes are displayed on this page.

   

4. (Optional) Click Add in the Backup Source page to add more nodes and provide the details in the Add Node dialog.
5. (Optional) Click the Exclude Volumes icon.

   The Exclude Volume Settings dialog opens which includes all the volumes of that node.

6. (Optional) Select the check box for each volume that you do not want to back up and click OK.

   The Exclude Volume Settings dialog closes.

   Note: To exclude a specific volume from all the backup nodes, enter the volume mount point names in Volumes to be excluded for all listed nodes. If you exclude the / volume or the /boot volume of a node, then you cannot perform a BMR of that node.

7. (Optional) Enter the files/folders in Files/Folders to be excluded for all listed nodes.

   The files/folders should be specified with an absolute path name and separated with a colon (:). Wildcard characters, such as * and ?are supported and should be used after the last slash of the absolute path name. If the files/folders name after the last slash is enclosed in parentheses, these files/folders will be excluded recursively, otherwise the files/folders will be excluded directly.

   For example:

   /home/user/a/foo*:/home/user/b/(foo*)
   

   The first part (home/user/a/foo*) will exclude only files/folders that match foo* under "/home/user/a", but it will back up sub-directories within. The second part (/home/user/b/(foo*) will exclude all the files/folders that match foo* under "/home/user/b", including all sub-folders.

   Notes:

   • If many files/folders are excluded from a volume, it is recommended to exclude the relevant volume.
   • If many files/folders are excluded, the job phase and status may stay "Backing up volume" and "Active" for a long time, when the backup job is launched.
   • If the value of Files/Folders to be excluded for all listed nodes is changed, the backup job will be converted to a full backup.

   If certain system files are excluded from the backup, then Linux OS may not boot, and the BMR function does not work properly. Such system files include, but not limited to:

   • Files and folders under /bin, /sbin, /usr, /etc, /lib, /lib64, /boot, /var
   • Folder /proc, /sys, /dev, /tmp

   If you exclude the system files, then it is recommended to verify the BMR function and confirm whether the Linux OS boots properly.

8. Click Next.

   The Backup Destination page opens.

The backup source is specified.
