1. A method of performing write operations for data storage from a client to a server having a local storage, comprising:
setting up a redirection threshold;
operating the server in normal mode, wherein ingest data is stored in the local storage;
continuously monitoring capacity utilization of the local storage;
when the capacity utilization surpasses the redirection threshold, operating the server in redirection mode, wherein ongoing ingest data is stored in the local storage and new ingest data is redirected to alternate storage remote from the local storage;
continuously monitoring storage utilization of the local storage and, when storage utilization of local storage drops below a predetermined recovery threshold, reverting the server to normal operating mode while continuing to redirect ongoing ingest data to the alternate storage; and
after reverting the server to normal operating mode copying all redirected data from the alternate storage to the local storage.
