What version OS are you using.

what command are you using to make fbackup.

also check this

The utility set comprised of fbackup and frecover was originally
designed for use on systems equipped with not more than one gigabyte
of total file system storage. Although the utilities have no
programming limitations that restrict users to this size, complete
backups and recoveries of substantially larger systems can cause a
large amount of system activity due to the amount of virtual memory
(swap space) used to store the indices. Users who want to use these
utilities, but are noticing poor system-wide performance due to the
size of the backup, are encouraged to back up their systems in
multiple smaller sessions, rather than attempting to back up the
entire system at one time.

These kind of messages comes when you try to backup very big data ( about 200GB)
It not so much of an issue backing up that amount of information in general. The
fbackup utility will create an INDEX of what it is about to backup, so this can
take up considerable amount of virtual memory depending on how many files you
have.
Basically you have one of three options.
1. Break up the backup - do one lvol at a time.
2. Use tar (a lot less elegant) but does not have the INDEX problem.
3. Increase the value of maxdsiz and see how you go.

This has to be done using SAM and you have to reboot the server to make it effective.. So downtime is required..

SAM ==> Kernel configuration and then go to tunables and select this parameter and then increase the value...
