Apple’s new iOS 10.3 update is going to arrive before the end of the month and while it is not a major update, there is one change that seems major for Apple internally as it changes the way file system works. Now, from the user’s perspective, you will have to be cautious and have a proper backup taken before you hit the update button.

For almost every update, we keep talking that backups and safety of the data, but let’s be frank. Most of the users don’t care about a backup because once the installation of the update happened without any problem, so that might continue and there is nothing to worry. But, at least in the case of iOS 10.3, make sure you take a backup of the data.

What’s changing in iOS 10.3?

It was always the HFS+ as the file system used in not just the iOS devices but also the Mac ones. The very old file system doesn’t do anything bad but Apple has decided to change that to the new Apple File System. The approach is not bad as the Apple File System carries a few good features including optimization for SSDs, Strong Encryption, Better time stamping for the files, and there are improvements to some other storage options for the files.

It isn’t only the iOS but in the coming time, the file system in MacOS, tvOS and even watchOS will be updated to the Apple File System.

Now, here’s why we recommend you to backup the data on your phone – Incompatibility of the two file systems with each other. While Apple will have it worked and do a smooth transition from HFS+ to the Apple File System but the thing is, it is an irreversible one so if in case the process gets an issue, there is no way you would be able to recover the data unless you had taken a backup.

Given the way Apple does the update process very well most of the time, you would usually not need to worry. But the file system change can go haywire, and even if Apple has a good process set up for that, it is a very strong suggestion to take a backup of the iPhone data.

How to take a backup of iOS device

Using iTunes – This is the best way as backing up with this method would help in the easy recovery of the data later. When you connect your device to the computer and then open Apple iTunes, you will see the section for that device and then click on “Back Up Now”. Encrypt the backup by setting up a password.

Using iCloud Backup – This is not a free option as we’re sure that long-term users of the iPhone will have a large data to backup and iCloud allows only about 5GB backup for free. If you are ready to pay, you can buy the storages with capacities of 50GB, 200GB, 1TB, or 2TB for different prices, but the problem here would be that you have to stay online and have a good connectivity for the update to happen.
