What Do You Know about Types of Data Backup?
What is "Data Backup"?
Data backup is the process of copying data from the primary location and storing it on the secondary computer system to protect against data loss,
especially in the event of hardware or software failure. Since the increasing reports of hacks, spear phishing, and harmful malware, it seems nearly
impossible to guarantee that your data won't be lost or altered. Don't think that data is only at risk digitally, physical disasters such as fire, and floods
can also erase all of your data. Losing any amount of data can jeopardize your privacy, cause huge damage and even disrupt business operations.
That's the reason why you should back up your data no matter if your data is personal or business-related.
Types of Backup:
There are numerous types of data backups and backup strategies that are created to address different issues, vulnerabilities, and storage
requirements. It might be challenging to determine which type of backup you need to perform to keep your business secure. You have to assess
how much data you have, what your network is capable of, and what you want the backup to achieve. You won't be able to find the best backup for
you until after that.
1. Full Backup
Full backup is the most fundamental and comprehensive kind pf backup operation. As the name implies, a full backup includes all of the chosen
files and folders backed up to a storage device, such as a disk or tape. It takes a longer time to finish and takes up more space than other backup
options. In a full ba
ckup, all data is duplicated and copied to a different location, and if restoration is required, retrieving it is faster with other backup
methods.
Pros: Less time to restore the data, easy to maintain and restore different backups
Cons: Takes a long time to perform a full backup, needs larger storage space
2. Incremental Backup
Incremental backup is a backup of all data changes since the previous backup was performed. This previous backup can be a full backup or the last
incremental backup. With this kind of, the first backup will be a full one, with repeating smaller incremental backups that replenish the data that has
changed over time. An incremental backup will only copy data since the last backup of any type, so an organization can run the backup as frequently
as needed, with only the most recent changes stored. The benefit of incremental backup is that it replicates a smaller amount of data than a complete
one. Thus, these operations will have faster backup speeds and need less storage space for the backup.
Pros: Backup is faster (only changed data is being backed up), and less storage space is used.
Cons: Despite having the fastest backup time, they make up for it by restoring the data much slower. It is due to the incremental data having to integrate
the previous backup which is an involved process.
3. Differential Backup
Differential backup stands in the middle of a full backup and incremental backup. It is because a differential backup saves all changes to data since its
last complete backup, whereas an incremental backup only records changes made since the last backup of any sort. Due to differential backups, a full
backup will be finished first, and the subsequent backups record the changes occurred since that full backup, thus, it takes longer time and needs more
space than incremental backups, although still take up less space than full backups.
Pros: Backup is much faster than a full backup, uses spaces more efficiently
Cons: Backup is slower than an incremental backup, not as space-efficient
4. Mirror Backup
A "mirror backup" is an exact copy of the original data. When a file in the source is deleted, the same file is eventually deleted from the mirror backup.
Running mirror backups should be utilized with caution due to the way they operate. If no one discovers before another backup, a file or folder that was
accidentally deleted (or even one that is deleted by the virus) will be lost in both backups.
Pros: Fast data recovery time, easy to access individual backed-up files, save storage space (backup doesn't contain old and obsolete files)
Cons: If files are deleted accidentally, they also be deleted on the mirror backup
