A natural disaster or calamity can happen at any time. In states like Texas and Oklahoma, it’s almost a certainty.
When disaster strikes, most people and businesses might hunker down and wait until it passes and they can continue with their lives. But some companies, especially service businesses, have to continue operations in the middle of a natural calamity because they simply can’t afford to stop. During these times, they have to rely on disaster recovery services in TX, OK, or other nearby locations to pull through.
At the center of disaster recovery is data recovery. Before experts can recover data, however, they need to back it up. Disaster recovery professionals recommend that a copy of the server data reside in an offsite backup server to prevent a single disaster from ruining both copies of the data.
There should also be a backup strategy. This must be composed of a schedule for a full backup, and the use of an incremental backup or a differential backup. Ideally, the schedule should allow for the completion of the backup process while the system is not in use. The full backup copies all the data in the server or the whole database. This takes a long time and can only be done about once a week.
Differential and Incremental Backups
In a differential backup, the backup server copies new information that has been added since the last full backup. If the full backup was completed on a Sunday, a Monday differential backup includes data saved on Monday. The differential backup on a Tuesday would contain the Monday and Tuesday data, and so on.
A differential backup is different from an incremental backup. An incremental backup saves data from the prior incremental backup up to that moment. An incremental backup on Monday, for instance, would save the data from the last backup until Monday. The succeeding Tuesday incremental backup would store only the data from the last backup on Monday until Tuesday. A Wednesday incremental backup would only store data from the last incremental backup on Tuesday until Wednesday.
Keeping a secure backup is important and is the first step to a disaster recovery solution. The use of a full backup with either differential or incremental backups is an efficient way of storing data. The use of an offsite backup center also makes sure that a single disaster or calamity will not take down the main server and the backup server at the same time.
