Backup (*.tis) Script File

Thread needs solution

Hello,

There are UPSs backing up source and destination NAS as well as intermedaite router and switch.  Would changing the *.tis script cache_network_write="false"  to True improve performance?

Have also observed cache_network_write="false" in *.tis script in ATI 2014.

Hello, asterger.

Well, I have talked to the developers and it seems that everything is a bit more complicated.

Apparently the default setting (cache_network_write="false") allows for maximum backup speed when backing up to a network share located on a PC with Windows XP and later. It also deals more gracefully with connection errors.

When the option is set to "true" it allows for compatibility with a wider range of devices, but the network/connection errors are not handled as well as with the default setting.

Now, it appears that you are backing up to a NAS and not to a Windows share. In this case it becomes more complex, as a NAS devices use very different implementations of the SMB protocol. So it is hard to tell what effect the parameter will have on your particular NAS.

I can only suggest that you check and compare performance by yourself. Please do so at your own risk, of course. (As you would be using an undocumented feature of the product).
