Choose cloud storage when you want photos and files available across devices and are comfortable managing an account and ongoing storage plan. Choose a computer backup with an external SSD or hard drive when you want an offline copy and can connect your phone regularly; use a mobile USB drive mainly for selected files, not as an assumed complete phone backup. Consider a higher-storage phone only when a verified backup and cleanup still leave too little local space for the apps and media you need.
For people whose photos, videos, downloads and apps are competing for phone storage and who need to free usable space without deleting the only copy. Android Help advises deleting local copies only after photos have been backed up.
For iPhone owners comparing iCloud backup, iCloud Photos, external-file copying and Mac or PC backup, including the encryption requirement for Health and Activity data in a local backup.
For Android users who prefer a computer, SSD or compatible USB route rather than relying only on a cloud subscription, and can check their phone, cable and transfer mode.
Start by deciding what must be preserved, then confirm the route works with your phone before clearing any local files.
| Priority | What to check | Your needs |
|---|---|---|
| Keep a verified copy | Check that uploads or transfers have completed; open recent photos and videos from the backup destination; confirm the destination has enough free capacity. | I want to recover usable phone space without removing the only accessible copy of important photos and videos. |
| Match the backup scope | Identify whether you need photos only, selected documents, app data, settings or messages. Check exclusions for the exact backup method and phone. | I need to know whether I am making a media copy or preserving a broader set of phone data. Apple Support distinguishes iCloud and computer backups from direct file copying. |
| Confirm device compatibility | Check the handset model, connector, operating system, drive format, adapter and data-capable cable. Confirm the exact drive model supports the intended host device. | I want a drive or cable that can actually transfer files with my phone and computer, rather than one that only shares the same connector shape. |
| Manage cloud capacity | Calculate storage used by photos, email, files and backups; review renewal, downgrade and account-recovery options; keep secure sign-in details accessible. | I want my cloud library to remain accessible without unexpectedly reaching a shared storage limit. Google One says its allowance is shared across Gmail, Drive and Google Photos. |
Different methods preserve different categories of data. Apple Support lists exclusions for iCloud and computer backups, while external storage is used for file copying through supported apps.
List what you need to keep before buying: photos and videos, selected documents, app data, settings, messages or Health and Activity data. Then check the documented scope for your exact phone.
Google Photos warns that device copies should be removed only after photos are backed up. Once local copies are gone, they may not appear in the built-in gallery or be available offline.
Open a sample of recent photos and videos from the backup destination, confirm that transfer or upload has finished, and retain a second copy of irreplaceable media before clearing the phone.
A matching plug does not confirm file transfer. Android Help notes that not all USB cables transfer files, and drive compatibility can depend on the host device and format.
Check the exact handset, operating-system version, cable data capability, adapter requirement, drive format and model-specific compatibility statement before purchase.
You may need a replacement adapter, data-capable cable or compatible drive if the original connection cannot transfer files.
For iPhone backups, Apple Support says encryption is needed to include Health, Activity and Keychain data, but the encryption password cannot be recovered if it is forgotten.
Store the backup-encryption password in a secure password manager or another secure record, and periodically check that the backup can be located and restored.

It is not confirmed for Lightning iPhones. Check phone read/write support, the file-management app and drive format before relying on it for transfers.
Not always. First identify what is using space, such as downloaded media, unused apps or cached data. If photos are the main issue, remove local copies only after checking they are backed up and accessible.
Yes, Google Photos can remove device copies after they have been safely backed up. Google Photos says the files remain viewable there, but they may no longer appear in the phone's built-in gallery or be available offline.
Do not assume so. Apple Support describes external storage as a way to copy files through supported apps, while Android Help describes USB transfer as moving files. Check the exact phone, app, drive format and cable before using a USB drive as a file-copy destination.
Check the exact phone connector, whether an adapter is needed, whether the cable carries data, the drive's supported file system, the phone operating system and the specific drive model's host compatibility. A USB-C connector alone does not confirm full compatibility.
Apple Support states that iCloud backup is encrypted and stored in iCloud, while computer backup is stored on a Mac or PC and can be encrypted. Both methods have exclusions; for a computer backup to include Health, Activity and Keychain data, encryption must be enabled and its password retained.
