What is off site backup?

What are the components of a good backup plan?
A good backup strategy has three parts: backups and archiving, disaster recovery, and business continuity. Periodic backups and archiving should be your first line of defense. When data is created or changed, your organization should back it up on a regular basis.
What data should be backed up and why?

What is the greatest advantage of local backups?
The benefits of local backup include the following:
- On-site accessibility. It doesn’t get much more accessible than having the backup data at your primary site.

Does backup require Internet?
In the local backup, the transfer of data within backup devices does not require internet connection, so the data transfer rate is extremely fast as compared to uploading data in the cloud. Backing up data in external hard drives usually take few moments depending on the data size being transferred.
What are the drawbacks of a full backup?
Disadvantages
- Redundant backups- since most files rarely change each full backup is merely a copy of the last which means a lot of storage space is wasted.
- Longer to perform- as everything is backed up all at once it takes longer than other forms of backup.
Why is it important to back up data regularly?
The purpose of the backup is to create a copy of data that can be recovered in the event of a primary data failure.

What happens during a full backup?
When you take a full backup, the first thing it does it issue a checkpoint. That’s why the full and all subsequent log backups have the same checkpoint LSN. The first four log backups all have the same database backup LSN because they occurred during the full backup. That doesn’t change until the full is done.
Why you need to back up in the same drive?
There’s another issue: A backup drive should only be plugged in when you’re backing up or restoring from a backup. Why? Because the same fire, flood, burglary or malware that destroys your main, internal storage could also destroy the backup. Ideally, your internal storage should be large enough for all of your files.
What are the drawbacks of backing up data to a cloud based disk?
Disadvantages of Cloud Storage
- Internet Connection. Cloud based storage is dependent on having an internet connection.
- Costs. There are additional costs for uploading and downloading files from the cloud.
- Hard Drives. Cloud storage is supposed to eliminate our dependency on hard drives right?
- Support.
- Privacy.

What are the disadvantages of data backup?
The Cons of Cloud Backup
- You can’t access your data if you don’t have Internet access.
- Bandwidth issues – You need the right amount of bandwidth to back up large chunks of data.
- Full data recovery could take some time – It is fast and easy to recover small quantities of data.

Why is tape backup still used?
Longevity of tapes is the main reason why tape backups are still widely used by large enterprises. If maintained properly, tape drives can store required data for 30 years or even more. As a result, tape backups can offer long-term retention of critical data and ensure high archival stability.
