Backing up data from tru64 to Restore on Linux

kravi75 — Sun, 27 Apr 2008 11:04:12 GMT

Customer wants to take around 180GB data backup from tru64 to restore on RHEL 4.0.

Seems Datas are more than 8GB file size and they have taken backup with tar -E option.

While trying to restore in linux, getting segmentation fault.

Isit due to taken the backup with E option in tru64?

Is there any other backup/restore utility which supports both the OS with large file sizes?

Pls advice

Thanks
Ravi

When tar fails, cpio could be your alternative.

Using what?

I believe that GNU "tar" is available on both
systems. It might make some sense to use the
same program at both ends. (Especially when
using features involving extensions to the
original "tar" format.)

Hello Ravi,

you can try cpio instead of tar.

Is there any way to copy the data directory, for example over scp?

Best regards,
Patrick

First question I have you have large file support in Linux???

And if you have taken backup using tar and you will have to restor it using tar only.
-E i do not think could be the reason.

Hi All,

Thanks for all your advice.

There are single file with more than 8GB sizes, hence not tried with cpio, since it also has limitation of file size.

Now we are trying with ftp option.

Thanks
Ravi

Why? If you're using the network for the
transfer, why not use a (GNU) "tar" pipeline?
If the data are compressible, and the CPUs
are not too old and slow, this would allow
easy compression, too. (While saving the
various file attributes, like ownership and
permissions.)
