Backup & recovery (data protection)
In the IT industry, storage is important to keep the sensitive data. The data can be lost if the primary storage device being crash or down. When the data is lost by something, it can be impacted by the business. Because the data is the most precious thing in Data Center. At there, we need to make a decision if the data is lost by something, where can we get the data again? So, backup solution plays an important role in the storage system. If our IT infrastructure has only the best storage system, it can’t called the data secured zone even we have no backup plan and solution. Having duplicate copies of your most important information saved in a remote location keeps it safe in case anything goes badly wrong with your computer.
When you think about it there are a number of ways files can be lost unexpectedly:
- Computer crashes
- The Human Eraser
- Physical Computer Damage
There are quite a number of backup types and terms used when it comes to backups of your digital content. This is a compilation of the most common types of backup with a brief explanation of their meaning, common examples, advantages, and disadvantages of each backup type.
When subsequent backups are run, the entire list of files and will be backed up again. The advantage of this backup restores is fast and easy as the complete list of files is stored each time.
Incremental backup is a backup of all changes made since the last backup. With incremental backups, one full backup is done first and subsequent backup runs are just the changes made since the last backup. Storage space used is much less than a full backup and less then with differential backups.
Local backups are any kind of backup where the storage medium is kept close at hand or in the same building as the source. It could be a backup done on a second internal hard drive, an attached external hard drive, CD/ DVD –ROM or Network Attached Storage (NAS). Local backups protect digital content from hard drive failures and virus attacks.
When the backup storage media is kept at a different geographic location from the source, this is known as an offsite backup. The backup may be done locally at first but once the storage medium is brought to another location, it becomes an offsite backup.
It is where data is backed up to a service or storage facility connected over the Internet. With the proper login credentials, that backup can then be accessed or restored from any other computer with Internet Access.I mean there are a lot of backup types but we should decide which one is more suitable with our organization infrastructure and I should one to back up.
And another one is the storage device to keep the backup data. For example, DELL EMC Data Domain device. DELL EMC Data Domain deduplication storage systems continue to revolutionize backup, archiving, and disaster recovery with high-speed, inline deduplication.
1.Reduce storage requirements by 10 to 30x
2.Complete more backups sooner with performance up to 31 TB/hr
3.Gain faster time-to-DR readiness through deduplication, reducing WAN requirements by up to 99%
4.Ensure your data is recoverable with the Data Domain Data Invulnerability Architecture
5.Speed your backups by up to 50% with Data Domain Boost software.
And then, there is backup software to perform backup solution, for example, Networker software. Deduplication of backup data is provided by integration with Dell EMC Data Domain (DD Boost) storage solutions.
In the backup, there are three types of the backup process.
- File-level backup
- VM-level backup
- Application-level backup
Which kinds of backup type will be used is based on the organization requirements.For the backup solution, we need to choose the best solution which can provide fast backups and recovery, protects data on-premises and in the cloud, and delivers a lower cost-to-protect with leading data deduplication and bandwidth utilization.So, we can protect our valuable data by using Backup Solution.
