Simple, customizable and easy to use.
Recently we had two errors on our main server. The first time we had a local power outage in the data center, the second time there was a hard disk error, followed by a system restart and RAID5 recovery. Both times the main server was inaccessible for more than 2 hours. During that time SpareSync had switched the platform to backup server and allowed the users to continue their work.
Since the first configuration SpareSync module is simple, customizable and easy to use, and any complications can be addressed to the tech support. The only problem we encountered was the server time difference. We had a virtual server and a physical one, that led to accumulated time difference (more than 30 sec) between main and backup servers, so SpareSync had to stop database synchronization.
