Whether you're a storage administrator at a large Fortune 500 company, or working at a small organization with fewer than 100 employees, chances are at one time you've had
But how much about small business backup do you really know? Take our quiz and test your data backup and recovery knowledge. If you got more answers wrong than you hoped for, or want to learn more about backup, check out our small business backup tutorial.
1. This is a strategy for backing up data that involves sending a copy of the data over a proprietary or public network to an offsite server. The server is usually hosted by a third-party service provider that charges the backup customer a fee based on capacity, bandwidth or number of users.
2. Also called a dynamic backup, this type of backup is performed on data even though it is actively accessible to users and may currently be in a state of being updated. These kinds of backups can provide a convenient solution in multi-user systems because they do not require downtime.
3. A major advantage of this technology is that it preserves a record of every transaction that takes place in the enterprise. In addition, if your system becomes infected with a virus or Trojan, or if a file becomes mutilated or corrupted and the problem is not discovered until some time later, it is always possible to recover the most recent clean copy of the affected file.
4. This type of backup can be conducted through a storage area network (SAN) or with a tape device directly attached to the storage subsystem. Some of the advantages of this type of backup include shorter backup and recovery times and less disruption to other systems and applications.
5. This is a set of reference markers, or pointers, to data stored on a disk drive, on a tape, or in a SAN. It is something like a detailed table of contents, but it is treated by the computer as a complete data backup.
6. This type of tape has a capacity of 3.2 TB, with data transfer rates up to 360 MBps.
7. This technology is often called "intelligent compression" or "single-instance storage," and is a method of reducing storage needs by eliminating redundant data. Only one unique instance of the data is actually retained on storage media, such as disk or tape. Redundant data is replaced with a pointer to the unique data copy.
8. The main advantage of these is that they can deliver the fast data backup and recovery times associated with SANs while also providing the portability of tape that may be required to meet corporate backup and recovery requirements. Hint: They are more expensive than tape.
9. This is the process of moving data that is no longer actively used to a separate data storage device for long-term retention.
10. This is is the repeated back and forth motion a tape drive makes when there is interruption in the data stream.
