Re: backup fail, how to prevent happening again

thanks Spenser ,

that's very helpful and good to know you are doing this (forcing the  
clients to quit prior to backup)
and that it works..

I've had a look at the command you point to - and this looks like the  
way forward
http://www.4d.com/4ddoc2004/CMU/CMU00648.HTM

if i have this in 'on Startup' - this will run when each 4d client is  
started up
so i will know who is logged in. - as you described. so there fore  
the clients  i should force quit
before the backup.

i just wanted to reassure myself on  an important point.
my only concern now is the use of a forced 'Quit 4D' for the client  
possibly in mid transaction.
eg mid  record edit
is there a possibility that the data file could be damaged if they  
have a form open within a transaction
or will the system gracefully 'roll these back' ?
I assume it will - as that's the point of a transaction
or should i attempt to quit each process on each client ...



.

thanks

John,

Register Clients and you can count them with Get Registered Clients and
instruct them to self-terminate with Execute On Client
("@";"MyQuitMethod")
`MyQuitMethod
Quit 4D
`end

We Register Client, On Startup with an interval of 10.  And, On Backup
Startup lets you cancel (just return non-zero) so we put up a dialog  
(click
to cancel backup) for 30 seconds before proceeding.

Hello John,
We forcefully quit the clients on every backup and have never had a data
corruption as a result, if that helps. But of course our experience is only
our experience.
