Data loss is not far from new. As there are so many cases about data loss and data leakage, protecting database and doing a good job of database backup become very important now.
How value a data backup actually is to us is a clear thing.
1. The optional data recovery has a higher priority after the failure.
2. Large data restoration is impossible and there is no need to be completely up to date.
3. As its large size, the cost of storage media for large data is unaffordable.
4. Storage and loading large data table are very expensive and time-consuming, because it may take a few days or weeks to complete a good restoration of the regular data storage.
Because of these circumstances, the data of the database is very importance. If you are not take it seriously, a large data deployment’s failure may affect the company's running directly.
Generally speaking, there are many ways for data backup, e.g.
1. The local and remote copy contains disk file backup and backup of database entity. The use of virtual snapshot is a hardware solution that allows storage medium to create a virtual backup of the entire system. The write operation of database is disabled in a short time and the storage subsystem of hardware management will handles all internal file’s backup jobs.
If you can successfully create a point-in-time snapshot, it will provide a very short recovery time. In addition, restoring to the point-in-time rather than the snapshot creation point requires some way to apply all recent database changes to the snapshot. Storage capacity is a big problem too, as a snapshot may require twice the current use of storage capacity. And another snapshot area must be allocated to prevent failure expansion if a failure occurs under the condition of the snapshot is used as the current data.
2. Automated recovery process.
Time is very important while restoring multiple databases. We need to review data recovery process regularly, and time for backup and recovery time will increase with the rising data capacity. Therefore, when you do the backup, just choose a high speed backup option, like virtual snapshots .
3. Recovery tests.
Almost all of the application environment will change over time, so the recovery process to be tested. And In this process, you need to identify which recovery processes are up-to-date, which one is recovery time and plan for future capacity changes.
Everybody knows that database is very powerful, and if we want the database to run better and safer we need check it regularly. And we should have a regular basis Backup processing, in the event of data loss, it will not cause too much damage.“Database backup is very important. You can seek help from professionals when you suffer from a data loss.” According to advice from engineer in Hdata Recovery Software.
