Hello Everybody,

We are using Red Hat Enterprise Linux 4. I have 2 queries.

1) I want to take FULL backup of the entire system 9/, /boot, /usr etc...) using the tar command. The command "tar -cvf <dat drive filename> /" does not work. I gave this command from the "/" partition. It takes backup of some files and comes out giving the error saying (...... no. of 10240 bytes written etc...).

2) I have tried giving the command "tar -cvf <dat drive filename> -L 25165824 /usr /usr1". Here in this command I am trying to take the /usr and /usr1 partitions backup on the dat whose size is 24 GB. The size of the /usr and /usr1 partition is 8.5 and 3.0 GB respectively. It just writes for around 15 minutes (approx. 250 MB) and asks for volume 2 to be loaded in the dat drive. The full capacity of the dat i.e. 24 GB) is not being used.

Kindly help.

Hello Everybody,

We are using Red Hat Enterprise Linux 4. I have 2 queries.

1) I want to take FULL backup of the entire system (i.e. all partitions - /, /boot, /usr, usr1, /home etc...) using the tar command. The command "tar -cvf /dev/sd0 /" or the command "tar -cvf /dev/sd0 ." given from the "/" partition does not work. (/dev/sd0 is the filename of the internal dat drive that is attached to the system). It takes backup of some files and comes out giving the error as follows :-
tar: /dev/sd0: Wrote only 6144 of 10240 bytes
tar: Error is not recoverable: exiting now.
The size of the dat loaded in the internal dat drive is 24 GB. It comes out giving the above error.

2) I have tried giving the command "tar -cvf /dev/sd0 -L 25165824 /usr /usr1" also. Here in this command, I am trying to take the tar backup of the /usr and /usr1 partitions backup on the dat whose size is 24 GB. The size of the /usr and /usr1 partitions are 8.5 GB and 3.0 GB respectively. It just writes for around 15 minutes (approx. 250 MB) and asks for volume 2 to be loaded in the dat drive. The full capacity of the dat i.e. 24 GB) is not being utilised.

Kindly help.
