icloud or computer?? which is better for back up?, icloud or computer?? which is better for back up?

Backing up to your computer is generally much faster, and restoring to a backup made on your computer is definitely much faster. Also, backups made on your computer include more data that iCloud backups (which don't included data that is assumed to be in your iCloud account such as your calendar). Backups made on your computer don't use your iCloud storage if you're running low on iCloud space. Finally, backups made on your computer happen as part of the sync process, so it requires you to be diligent about syncing your phone.

Backing up to iCloud offers greater convenience as it automatically backs up your phone every 24 hours as long as your phone is connected to wifi and you charger. This ensures that it is backed up every night.

I usually recommed that people do both. Back up to iCloud daily, then perform a manual backup on your computer at least once a month by right-clicking on the name of your phone on the left side of iTunes and selecting Back Up. This gives you the best of both, and has the added assurance of a second backup in case one of them fails.

Hi , if I have backed up my data on iCloud>iTunes instead of this computer>iTunes . Will I able to retrieve data back if i use another computer not the same computer I used to back the data up.

My query is I want to retrieve data back on another (different computer) after logging in iTunes as I lost my earlier computer however i backed my data on iCloud>iTunes only
