The questions of some common data backups
Repeating deletion of data and data compaction can cut down the performance requirement of data storage greatly, can save more than 90% of the data backups. The machine format reduction of the backup can reduce the cost of hardware and management. However, small and medium enterprises and departments are often unable to employ the technology, there are some reasons here, among them have inadequate experience on including practical operation.
The following is the questions of some common data backups:
1. Should we use and repeat the deletion of data or data compaction or both use?
Use. Repeat the technology that deletion of data and data compaction are relatively independent and can be complementary, use the data backup that can reduce more than 90% together. On it use singly,though that in these two kinds of technologies is one kind of arbitrary can reduction magnetic disc backups valid, but whole data it reduces strategy to be to include, repeat the intersection of data and deletion and the intersection of data compaction and two these. If you use achievable 2 of the data compression techniques: The backup data reduction ratio of 1, use and repeat the data to delete achievable 10: The backup data reduction ratio of 1, can reduce the proportion of total data backup and reach 20 altogether then: 1.
2. On the basis of data compaction of hardware, or based on software data compaction well?
Here needs to consider two respects, especially need to consider the handling capacity of data compaction, so will consider its impact on backup characteristic when disposing a solution based on hardware. The gas-booster of data based on hardware also has a compatible advantage that disposes the utility program in advance, and does not need buying, install, those scrappy products of disposition and management. While looking for the data backup to reduce the apparatus, don’t consider the single backup server, because it will increase the complexity of the backup, and increase the whole cost of the infrastructure of backup. A style ” The full-function ” The backup data reduction apparatus needs to have many kinds of solutions.
3. The tape back-up system includes data compaction. Why can’t we use the hardware to compress in the back-up system of the magnetic disc?
The magnetic disc is compressed and based on the file traditionally. It is finished on the data block that the hardware is compressed, but not on the file. Until recently, the difficult problem based on data compaction of one on the hard disk was not solved. The backup apparatus of data compaction introduces the magnetic disc based on hardware to compress until now.
4. How are remote server backup and strange land backup used for disaster backup?
The data compaction of the backup must solve the backup servers of general headquarters and long-range shop, and send the backup data to the disaster and resume DR The station is had. The backup should be single, lasting, centralized and facilitating management.
5. Do the same data reduce the apparatus and can be used in the mainly machine format backup?
Generally, repeat the data and delete and compress and use in the master data in different way. The main memory on the data block repeats the data to delete and apply to the magnetic disc. Beginning of Windows and Linux filing system in the data block. This means, mainly store and repeat the data and delete and discern the repeated data block in the file all the time. In addition, the repetitional data can be measured out in the database or across the database. On the other hand, the utility program create file of the backup. tar和.zip file is equivalent, this data block will not be always arranged in the same way, so backup repeated data delete utility program, repeat data, delete than master data difficult to make many.
6. Why is gas-booster price of the data changed so largely?
Only the comparative price is incorrect. The cost of every TB magnetic disc backup should be a standard tested and assessed. How much it can supported that the backup runs side by side? Which are there on influence of the backup characteristic? If you do not know these questions, then you will spend more fund buying the ABC of grade of products.
