Image-based backups VS file based back-ups are tricky.
Knowing when you should use which is even harder.
Knowing what is best for you comes down to what kind of information you are looking to save and back-up.
Let’s go over the difference and what would be best for you and your company.
The main question is … What are you looking to recover?
Difference Between Image VS File-Based Backup’s
Image-based backups preserve a copy of a machine’s operating system. That includes system state and application configurations, as well as the data associated with that machine. It’s basically an image of your entire operating system including files, executive programs, and OS configurations. It works best if it is necessary to bac k up a VMware or Hyper-V virtual machine. This is very simple to configure type of backup where you just select an entire drive, partition, or an entire machine, which typically backs up the entire selection you have selected.
File-based backups will back up each file on your PC. It will save the files, but not the applications that created them. If you did not setup your file backup to save “all” the documents on your machine, then you won’t be able to restore them. It is reasonable when it is necessary to copy separate files so that they can be recovered to any other system. File backups basically come down to you selecting some files and folders that you want to back up and then where you want those file level backups to go.
File-based backups are usually more flexible way to doing backups, scheduling, and are normally smaller backups.
Image-based backups are usually better in disaster scenarios when an entire system restore is required.
What Type of Backup is Recommended?
Now that we have established the difference between the two, the major question stands … Which one is recommended? Both is adequate when having back-ups.
A good backup setup would usually include:
1. An image backup once a month.
2. A full file level backup once a week.
3. A differential file level backup every day other than the full backup day.
This type of schedule will most often help give you an easy and quick way to get files and folders back. Having extra backup to be able to recover any and all files will be a huge impact to your business information.
