Why iCloud takes long to backup?

Hello Apple, every time I backup, it takes many hours to back up and I only use up to 30 GB of storage. What can I do? Please help me.

- Question from Apple Community

If you are an iPhone user, you must be familiar with iCloud, which was released by Apple as a built-in application on iPhone. You can use iCloud to backup your iPhone, you can easily restore the whole iPhone data to a new iPhone as well. But sometimes you will find iCloud backup taking days especially when you backup your iPhone for the first time. Keep reading this passage and learn more about iCloud backup.

Part 1. How long does iCloud backup take on iPhone?

How long does iCloud backup take on iPhone? Let’s get started to figure out how the three aspects influence the iCloud backup time.

▶ Data Amount. It may take 30 minutes to 2 hours for iCloud to backup your iPhone for the first time, because the size of files which iCloud backs up will influence the duration directly.

Wi-Fi Condition. Wi-Fi condition is another aspect that can directly influence the duration. Since iCloud is a network application, a fast and stable speed of internet connection (your upload speed instead of the download speed) is a prerequisite for iCloud to backup well. If the upload speed is around 1 Mbps, it may take around 2 hours to upload 1 GB files.

iPhone Condition. You may find your iCloud backup time keeping increasing after you have used your iPhone for a long time. If your storage is nearly full, it means that its performance is getting worse. Thus, iCloud backup time keeps increasing correspondingly.

Icloud Backup Stuck

All in all, for the question “how long does iCloud backup take on iPhone”, the answer is uncertain. If you try to backup thousands of photos, videos or other types of files, it’s no doubt that iCloud backup can take 1 or 2 hours or even take days. Even if you have a good backup habit and you backup once a week, iCloud also runs for about 7-10 minutes every time.

Tip 1. iCloud can also automatically backup your iPhone if you 1) turn on iCloud Backup. 2) connect your iPhone to a stable Wi-Fi network. 3) have enough available space in iCloud for the backup.
Tip 2. Backup iPhone automatically with iCloud in details.
turn on iCloud Backup > [your name] > iCloud > iCloud Backup and toggle iCloud Backup to on.

Part 2. Back up iPhone to computer to avoid iCloud issues

Besides the aspects we have mentioned above that slow down the process of iCloud backup, other demerits of iCloud can also be seen.

Limited storeage space. iCloud only provides you 5GB of storage space to backup which is far from enough. You have to pay monthly for more space, and how much you pay depends on how much space you want to get.
A waste of the storage space. iCloud backs up almost everything from your iPhone, such as your iPhone settings and your purchase history which you don’t mean to backup. It’s also the reason why your 5 GB space runs out quickly. Thus, you may suddenly find that your iPhone backup failed for not enough space in Cloud.
