You're worrying about nothing.
This _is_ telling you that some files which were present when the mksysb
started, and determined what to back up, had been deleted by the time the
mksysb got to them. It is common on any system that is not idle. It's
often print files, or temporary logs, so you find it for /tmp and /var
files. There should be messages - possibly in stderr, rather than stdout -
which tell you which specific files were not backed up.
The message...
31776 of 37047 files (85%)..........................
...is at 85%; just a progress message and does not indicate the end of the
backup. It doesn't produce another message on reaching 100%. 31776/37047 ~
0.85.
Some types of file cannot be backed up, and will cause mksysb to fail. This
includes some types used by databases. Also, you may not be able to restore
database files correctly from a mksysb/savevg. Always use the correct tool,
as recommended by the database supplier, for backup and recovery.
Backing up open files may produce inconsistent results. For simple flat
files this is not usually a problem: each individual file is backed up OK.
The problem comes when an application is updating two files concurrently.
The backup works sequentially so the files may be out of step, rendering
them useless to the application. This is particularly relevant for database
management systems, such as Oracle.
