Any idea about fbackup limitation.

[Rajesh SB]

Hi,

Is there any limit in size of file like 2GB (nolargefile) using fbackup. I would like to know limitation if any using fbackup.

Regards,
Rajesh

Hi Rajesh:

'fbackup' handles largefiles (> 2GB) just fine.

Not for fbackup.

This is for cpio, pax and tar, and that too can be raised to 8GB with a certain patch.

There is no limitation of 2GB in fbackup. It is only limited by tape library.

Hi,

From man fbackup
++++++++++++++++++++

Due to present file-system limitations, files whose inode data, but not their contents, are modified while a backup is in progress might be omitted from the next incremental backup of the same graph. Also,fbackup does not reset the inode change times of files to their original values.



With release 10.20, HP-UX supports large files (greater than 2GB) and increased UID/GIDs (greater than 60,000). Archives containing files with these attributes would cause severe problems on systems that do not support the increased sizes. For this reason, fbackup creates tapes with a new magic number ("FBACKUP_LABEL"). This prevents fbackup tape archives from being restored on pre-10.20 HP-UX systems. frecover still reads both tape formats so that fbackup tape archives created on pre-10.20 HP-UX systems can be restored.


Precaution - While restoring a backup having files of size more than 2Gb, the destination file system should be supporting files above 2GB within same os as well.

No limitation for 2 GB.
I used fbackup before to backup 15 GB data.
