![]() it is costly as you will be required to have more than one device especially if you have your storage as a safe deposit box. This is so that you may ensure that the offsite location is not susceptible to risk. For instance, it requires a thorough audit to be done before it is implemented. It, however, has a number of disadvantages. The perks of offsite backup are quite obvious: you are protected from hurricanes, fire or theft. They work the same way local backup does but then eliminating the probability of theft or natural disasters. It could mean that you have taken the drive home, to your safe deposit box and to another building. If the storage medium is taken to a different location, then it is an offsite backup. And yes, the backup may be done locally and stored in an external hard disk. Provided that the backup is stored in a geographically separate location, the type of backup is offsite. The chances of the source being damaged equal those of the backup being destroyed too. The close at hand type of storage, however, makes the data more vulnerable to theft and natural calamities. Also, you have full control over your data as you do not have to assign it to third parties. The proximity of the backup makes it easily accessible in the event that you may require restoration to be done. The cost of data transfer and storage is very low. The process of back up and restoration is fast. The major advantage is that with local back up, you are safe from virus attacks, hardware malfunction, and sabotage. Well, local backup tends to have an endless list of advantages since there exists different types. Good examples are optical drives such as CDs, internal hard drive, external hard drive and Network Attached Storage to mention a few. In most cases of local backup, the storage device is connected directly to the source or through a network. It simply refers to back up that is stored at close proximity. Local backup is probably familiar to many. Additionally, the restoration process is slow and complex. It is not as efficient with storage as an incremental backup is. It also has its share of drawbacks, whereby the backups are slower than incremental. The other advantage it has is over incremental backup, whereby it restores backup data much faster than incremental does. The changes are the only ones that will be backed up in differential backup. ![]() Also, it is more efficient on storage space as opposed to a full backup which repeatedly stores already existing files. The pros of a differential backup are that it is much faster than a full backup is.
