Backup jobs hangs in Preprocessing while backing up SUSE Linux Server.


 This issue occurs if Ipv6 is enabled on the SUSE server. 


To verify the same run the following command on the linux server.
  1. Login as root.
  2. At the command line type ifconfig press enter.

This will list the available network adapters and its configuration details. If you see lines containing inet6 as shown below then Ipv6 is enabled.

eth0    Link encap:Ethernet  HWaddr 00:0F:1F:89:8F:D5
         inet addr:  Bcast:  Mask:
         inet6 addr: fe80::20f:1fff:fe98:5fd8/64 Scope:Link

Disable Ipv6 using one of the following methods.

Method 1
Using YAST (System management Tool)

  1. Open YAST
  2. Select Network Devices.
  3. Select Network card.
  4. Open the Network Setup Method.

Select the Network card in use. Open Advanced settings and select disable IPv6.

Method 2
Using Command line (Linux Terminal Window)

# echo "alias net-pf-10 off" >> /etc/modprobe.conf.local
# echo "alias ipv6 off" >> /etc/modprobe.conf.local

Restart of the server is required. Once the server has been restarted run ifconfig again to verify if the inet6 lines have been removed.

Note:- Verify the /etc/hosts file and comment any Ipv6 entries present in the file. The entries in the hosts file would be similar as listed in example below;

# ::1             localhost ipv6-localhost ipv6-loopback
# fe00::0         ipv6-localnet
# ff00::0         ipv6-server

Once Ipv6 has completely disabled then retry the backups.
