Hi,
The server I am working on currently is an HP ML110 (Tower Server), which is not a powerful one. It has 8 GB of Ram which 5 GB of it is being used by the application running on the server. Since it is an old server it only supports SATA Hard Drive and it does not have one of those warning LED lights to show whether the hard is in good condition or not. The application which is running on the server is a localized version of a sharepoint designed with Oracle. (letters and documents are scanned and being stored on this server and then send to the office workers in the network. These documents then being studied and reviewed by the mentioned office workers and then they write their comments and actions on a special tab).
Due to financial limitations I have bought an external USB hard drive as an external drive to hold my once in a day backups. My question is, by considering the weakness of my server (HDD seems to be the bottleneck sometimes) which version of backup is recommended after the initial "Full Server Normal Backup"? Shall I go on with the Normal Backup Performance or Faster Backup Performance using incremental backups?
