MYSQL Backup addon error

[DrByte]

Well after nosing around I learned that, despite the Zen instruction to turn on safe mode, this backup utility will not function if it is on. All the buttons etc. appear but it won't work. I either have to leave safe mode off or remember to turn it off when I want to do a backup.

I'm not sure what "Zen instruction to turn on safe mode" you're referring to.
Zen Cart has *always* recommended against the use of safe mode, as there are many far more efficient and effective ways to secure a server other than the overly restrictive safe mode in PHP.

So, yes, turn off safe mode. The warning message in the backup_mysql tool specifically says that it typically won't work if safe mode is turned on.

This addon has been work great on our site almost one years, but recently after i add 10,000 more products, and database size increases from 10MB to 135MB(.sql format), backup become not work well, the download result is 0 Byte.

I am wondering if this model has any restrict like size of database or something else? Hopefully somebody can give some tips how can i get backup success again. Because it bring so much convenience to backup.

Appreciate very much for your time!

I have no idea why yours is having problems. I regularly use it to backup a 2GB database with no problems (takes about 2 minutes, during which the server appears frozen, but otherwise works fine).
