• Backup: A backup is a copy of a file or other piece of data. When you start a backup, it copies your files. These duplicates are stored in a different location. Depending on the amount of data you're backing up, backups can take a long time to complete.
• SNAPSHOT: Snapshots are a kind of "picture" of your server's file system that you can take at any time. This picture accurately depicts the server at the time it was taken. SERVERS can be restored using snapshots by restoring them to the state they were in when the snapshot was taken.

The following points illustrate the differences between snapshot and backup:

• Backups can be kept in multiple places, on the same disk, or even on the same server. They don't necessitate both off- and on-site storage. Snapshots necessitate both on-site and off-site storage, and they must always be kept in the same locations as the original system data.
• Backups for SQL servers are normally done through a subscription service. The operations INVOLVED in creating snapshots are normally free and can be done at any time.
• When it comes to backups, there can be discrepancies between when they started and when they finished. Snapshots are "pictures" of your server that retain it in its current state.
• Making backups can be a time-consuming and LABORIOUS task. Snapshots are instantaneous and take a fraction of the time. Snapshots also save time when copying data.
• Only the file system is INCLUDED in backup files. Different types of systems can be captured in snapshots. Files, programs, settings, and other items fall into this category.
• Backups are saved in various locations and can be readily recovered. Backups are frequently verifiable as well. Snapshots aren't the same thing as backups. They can (and should) be utilised as a part of the backup process, but they are primarily short-term solutions. When a backup is finished, snapshots are removed.
