ACS Multiple Cloud Queries, how to best manage?

Hello,

I am writing an app that has to upload large amount of new custom objects / photos to ACS (to backup after the app comes back to a data connection) and was wondering what the best practise / methods to do this are? For instance if my code needs to do the following (roughly)

//customObjectsArray has 50 objects
//photoArray has 75 photos
 
For (var x = 0; x < customObjectArray.length; xx){
    uploadCustomObjectIntoACS(customObjectArray[x]);
}
 
 
 
For (var x = 0; x < photoArray.length; x++){  
    uploadPhotoToACS(photoArray[x]);
}

Can we just run it like this, or is there a max number of connections or limit to the rate you can call cloud queries? I have tried to upload large sets of new objects in a for loop and it seems to refuse the connection after a bit (not surprising).

However, when I rewrote it to be recursive with the cloud call back function it would take forever to upload that many photos.

Thanks for the help.
