file sizes don't match

Netbackup 7.7.3

RHEL master and media servers

AIX client

I am creating a validation step in my script that compares the filesize with netbackup output before deleting the file from the server. The file shows it's backed up but size doesn't match.

bash-4.2$ /usr/openv/netbackup/bin/bplist -l -b /backup1/ENCTRDRD/EXPORTS/hist_maee_record_proc_cycle_id_2067.dmp

-rw-r----- oracle    oinstall    24422972K Oct 28 05:00 /backup1/ENCTRDRD/EXPORTS/hist_maee_record_proc_cycle_id_2067.dmp

-rw-r----- oracle    oinstall    24422972K Oct 25 16:52 /backup1/ENCTRDRD/EXPORTS/hist_maee_record_proc_cycle_id_2067.dmp

bash-4.2$ ls -la /backup1/ENCTRDRD/EXPORTS/hist_maee_record_proc_cycle_id_2067.dmp

-rw-r-----    1 oracle   oinstall 25009123328 Sep 30 10:02 /backup1/ENCTRDRD/EXPORTS/hist_maee_record_proc_cycle_id_2067.dmp

bash-4.2$ du -k /backup1/ENCTRDRD/EXPORTS/hist_maee_record_proc_cycle_id_2067.dmp

24423156        /backup1/ENCTRDRD/EXPORTS/hist_maee_record_proc_cycle_id_2067.dmp

If I did my math right, 184K less in backup file showing (not to say when restored it's not the same size)

Are you sure? 24,422,972 KB which NBU bplist gives is the same as 25,009,123,328 from the OS "ls -al" command. I suspect the "du" command which reports a slightly higher number may include some filesystem block allocation rounding-up and/or similar artifacts.

I don't see a problem..

24422972K   means

24422972 * 1024 =  25009123328

which is correct.

Try du -kh  (not sure though if that works in AIX..)

Yes, it appears that the du -k is a bit off but using the byte size from ls -la / 1024 works out.

Thanks
