The tape backup software needs to read the tape catalog to find the correct files to restore, locate the correct tape, mount the tape, and read the data from it. When data needs to be durably stored on tape, multiple copies are required.
The time and effort required for backup and for recovery operations proved to be a significant improvement over tape, with restoring from Amazon S3 running from two to twelve times faster than a similar restore from tape. This eliminates the burden of budgeting for capital equipment well in advance as well as the capital expense.
Performance advantage and cost competitiveness. Maintaining reliable backups and being fast and efficient when retrieving data requires a lot of time and effort with tape.
With Amazon S3, teams simply pay for what they use, and are billed for their usage as they go. However, if there is a hardware failure, human intervention is necessary to restore from tape. This adds to the recovery time objective RTO and makes achieving it more challenging compared to backing up to Cloud storage.
After this one-time setup, the database backups were transparently redirected to Amazon S3. At the same time, Amazon. With the durability and availability of Amazon S3, these issues are no longer a concern.
During that time, managing tape infrastructure required highly skilled staff to spend time with setup, certification and engineering archive planning instead of on higher value projects. That cost benefit analysis included the following elements: Why Amazon Web Services Amazon. It was important that the overall costs of the backups did not increase.
Significant capital expenditures were required over the years for tape hardware, data center space for this hardware, and enterprise licensing fees for tape software.
There are virtually no upper limits as to how much data can be stored in Amazon S3, and so there are no worries about running out of resources.
The cost of backup software required to support multiple tape devices sneaks up on you. As part of that evaluation, they considered security, availability, and performance aspects of Amazon S3 backups.
Amazon S3 is designed to provide Backing up to on-premises disk based storage would have improved performance, but missed on cost competitiveness. One such innovation has been to replace tape with Amazon S3 storage for database backups.
Amazon S3 Cloud based storage met both criteria.
Utilization and capacity planning is complex, and time and capital expense budget are at a premium. This is especially severe during critical events such as a data center outage, when many databases must be restored simultaneously and as soon as possible.
Freeing up valuable human resources.
The company was able to replace their backup tape infrastructure with cloud-based Amazon S3 storage, eliminate backup software, and experienced a 12X performance improvement, reducing restore time from around 15 hours to 2.
These plans are then used to charge each organization for their tape usage, spreading the cost among many teams. This has caused growing pains related to backing up legacy Oracle databases to tape and led to the consideration of alternate strategies including the use of Cloud services of Amazon Web Services AWSa subsidiary of Amazon.
In almost all cases the data is spread across multiple tapes, resulting in further delays. Immediate availability of data for restoring — no need to locate or retrieve physical tapes. In addition, since Amazon. As one example, in a benchmark test a DBA was able to restore 3. This amounts to 25 gigabytes per minute, or MB per second.
Backing up a database to Amazon S3 can be two to twelve times faster than with tape drives. The cost of this software was an ongoing budgeting pain point, but one that was difficult to address as long as backups needed to be written to tape devices.
For teams adopting Amazon S3 backups, the need for formal planning has been all but eliminated.Garmin International - Exadata MAA for database consolidation with Oracle E-Business, Oracle RAC, ASM, Data Guard, RMAN case study A Real-World Technical Case Study of a Global Manufacturer: E-Business Suite, Oracle Exadata, and Oracle MAA.
