copy files while Backup Agent is running->error 46

Hi Btrivieans!

Bill Bach wrote as reply to the problm described at the end of ths post:
I would definitely recommend upgrading to SP3 (v8.7) as the first step.

Well, we do the upgrade and a couple of weeks there were no problms. But
yesterday we observe the following:

backup-agent was started exactly at 12:30 h, several datafiles where at this
moment not open especially a (btrieve-)file named pattest.dat.

While running PBA the datafiles are copied (with XCOPY). The copy job lastes
until 12:36 h. Meanwhile, at 12:33 h somebody used a function of the application
that needs pattest.dat, henceforce it was opened: in the PBA-Log appear

I 1612 04.10.2007 12:33:34 Backup Agent is now ON for this file:
"D:\project\DATS\PATTEST.DAT"

the strange thing is, that just after this at we get Error 46 on update and
add-operations on that file pattest.dat (not on open or read).
This Error 46 comes for every update/add until 12:59(! yes 59!) although the PBA
was OFF since 12:26 (as listed in the Log-File). The PBA is swiched off not
before the copy-action is finished (so the copy was ready at 12:26.).

There were also other btrieve-files opened at 12:33:34, but with them no problem
occur.

I can not explain this behavior. I guess, that at the moment of switching PBA on
for pattest.dat (12:33:34) the copy of that file was just in progress. But than
the error should be gone at leasat at 12:36.
But eaven if the error hat gone at 12:36 it remains the question: why occur this
error in the first place? I thgought, that PBA will tolerate copiing of the
originalfiles while running?

(of course *.^^^are not copied!).

As far as I know, the virusscanner is configured, so that *.dat and *.^^^ are
not scanned.

(In the PVSW.LOG file is nothing this time.)

Do you have any idea, what happens?

Sincerely
Mircea






Hallo Btrivieans!

since a couple of weeks we observe, that sometimes - not ever - PSQL engine 8.1
stops while Backup Agent is switched off:
Backup Agent runs twice a day, 12:30 and 20:00 a clock. Many times it work
without problm, but sometimes for some reasen I dont konow, the PSQL engine
simple stop work: here whats in the pvsw.log-file

(entries before 12:35:58 are not from 07-10-2007!)

(We have already exclude the btrieve-datafiles from virus-scanning.)

Is this phenomenon known? Will it make sense to update to 8.6 (i.e. is it a
known issus in 8.1)?


Any hint will be welcome
