Instructions to setup swap file

Instructions to setup swap file

Select the partition where you want to create the swap file. This partition must have free disk space to create the swap file.

Create a file for swap with the following command (# is shell prompt):

#dd if=/dev/zero of=/var/swapfile bs=1024 count=[count]

where [count]= number of 1024 blocks required. If count=1024000 size of /var/swapfile will be 1024* 1024000 = 1 GB .

You can decide the size of “/var/swapfile” depending on the size of the backup tar file.

Setup an extra swap with the following command:

#mkswap /var/swapfile

Enable “/var/swapfile” for swapping with the following command:

#swapon /var/swapfile

Verification: The file “/proc/swaps” must contain the entry for the swap file “/var/swapfile”. If this entry is not present, then swapping has not been enabled for the swap area.
