What OS / server type is your media server?
Do you have size_data_buffers set to a number greater than 64K for =
backups?
Are you restoring from disk or tape?
=20
Notes from Veritas support docs -
=20
VERITAS NetBackup uses variable length tape block sizes which =
correspond to
the data buffers used by NetBackup. However, in Windows NT, Windows =
2000 and
Windows XP the variable block sizes are limited to 64KB. With some SCSI
adapters and host bus adapters (HBAs), this limit is 128KB. As a =
result,
data buffers on Windows media servers are limited to 64KB as well. =
Failure
to follow this guideline can cause the inability to restore backed up =
data
and may result in messages such as the backup image
=20
By default the size of Windows data buffers is set to 64KB. This can =
be
modified by creating the
<install_path>\netbackup\db\config\SIZE_DATA_BUFFERS file (where
<install_path> is the path in which NetBackup was installed. By =
default,
this is c:\Program Files\VERITAS) and populating it with a value
representing the size (in bytes) of the data buffer.
Workaround:
It may be possible to temporarily work around problems with restores by
enabling fixed length blocks. This is done on the media server involved =
in
the restore by performing the following steps:=20
1) Create the following file:
<install_path>\netbackup\db\config\FIXED_LENGTH_BLOCKS=20
2) Stop and restart the NetBackup services=20
3) Attempt the restore that had failed previously=20
4) After the restore is complete, remove the FIXED_LENGTH_BLOCKS file =
and by
stopping and restarting NetBackup services
Solution:
Ensure that the <install_path>\netbackup\db\config\SIZE_DATA_BUFFERS =
file on
the Windows media servers does not have a value greater than 65536 in =
it. If
changes were made to this file, stop and restart the NetBackup services =
on
the Windows media server.
The technical details regarding the limitation of variable block sizes =
to
64KB is described in Microsoft Technet article Q152518 (Tape Variable
Blocksize Limited to 64K Bytes).

Are you using the rman scripts to do the restore?

Se the rman logs to know the reason of the error.
