Who this backup advice suits

Mixed-device households protecting family photos

For households using Apple, Android, Windows or Mac devices that want recent copies available after a phone or computer is lost, damaged or replaced. Automatic backup and dependable account access are especially important; Apple, Google and Microsoft describe different backup scopes and restore conditions.

Households with large photo and video libraries

For people whose photo and video collections may outgrow included cloud allowances or take time to transfer. Size storage for current files and future growth, then keep a separate recovery copy.

Privacy- and offline-recovery-conscious households

For people who want a copy they physically control or a recovery route that does not depend solely on one online account. The National Cyber Security Centre advises keeping backups separate from the original data location.

What to check before choosing

Start with the files you need to recover, then check where the copy will live, how it is updated and how you will restore it when a device is unavailable.

Priority What to check Your needs
Separate, recoverable copies Keep a copy away from the original device; check that files can be restored; avoid leaving an external backup permanently connected. I want photos and documents to remain recoverable after loss, damage, accidental deletion or malware.
Capacity and backup scope Measure photos, videos, documents and any required device backups; allow for growth; check which folders, media types and device data are included. My storage needs to cover the files that matter, rather than only a small selection or a free allowance.
Device compatibility Check operating-system support, ports, cables and file-system requirements; confirm whether photos are synchronised separately from device backup. I need a route that works across the phones, tablets and computers in our household.
Account access and security Review account-recovery details, protect the recovery email account and enable two-step verification for cloud storage. I want to retain access to the account that holds the cloud copy when a device is replaced.

Backup mistakes to avoid

  • Treating the original device or NAS as the only copy

    Loss, theft, failure, accidental deletion or malware can remove access to the only available copy. A backup needs to be separate and restorable.

    Keep at least one separate backup copy and add an off-site route for files that cannot be replaced.

  • Assuming cloud sync covers every file and every recovery situation

    Cloud services can differ in what is synchronised, what is included in device backup, what can be restored and how much storage is available. Apple, Google and Microsoft each document conditions that can affect coverage or restoration.

    Check the included data categories, storage allowance, deletion and version-recovery rules, and the most recent successful backup before relying on a service.

    Extra cloud storage may require a subscription when the included allowance is insufficient. Microsoft states that whole-OneDrive restore is a Microsoft 365 subscriber feature.

  • Leaving a removable backup drive permanently connected

    A connected drive may be exposed alongside the computer during malware or ransomware incidents, reducing the value of the separate copy.

    Run the backup, safely disconnect the drive and store it in a different safe location when it is not in use.

  • Buying a fast portable SSD without checking host compatibility

    Quoted transfer speeds can depend on the USB generation and host support, while mixed-device use may require compatible connectors or reformatting.

    Check every household device’s ports, cable requirements, operating-system support and file-system compatibility before purchase.

Relevant backup platforms and brands

Apple

iCloud is relevant to Apple-device households seeking integrated photo synchronisation and iPhone or iPad backup when replacing a lost or damaged device.

  • Apple states that iCloud can keep selected data updated across devices and automatically back up iPhone or iPad data.
  • iCloud Photos is synchronised separately from iCloud Backup, so check which data is protected by sync and which is in the device backup. Apple states that the free storage allowance is 5 GB and additional storage requires iCloud+.

Google

Google Account and Google One backup are relevant to Android households that want automatic Google Photos backup and access from signed-in devices.

  • Google states that Android backup can include selected photos, videos and device data, and backups can be automatic.
  • Google notes that restoration varies by phone and Android version, and not all apps can back up or restore all settings and data. Check file-size and format conditions for unusual camera files or large media.

Microsoft

Windows Backup and OneDrive are relevant to Windows households that need selected PC folders, settings and some app-related information available after moving to a new PC.

  • Microsoft states that Windows Backup uses a Microsoft account and can synchronise selected folders through OneDrive.
  • A free Microsoft account includes 5 GB of OneDrive storage. Microsoft says whole-OneDrive restore is limited to Microsoft 365 subscribers and can affect files created after the chosen restore point.

Samsung

Samsung portable SSDs are relevant as compact removable storage for transferring large local photo or video libraries between compatible devices.

  • For the T7, Samsung claims up to 1,050 MB/s read and 1,000 MB/s write under specified USB 3.2 Gen 2 and UASP conditions.
  • Performance varies with the host configuration, and operating-system compatibility may require reformatting. Confirm connections and file-system support before using one drive across a mixed-device household.

Synology

Synology NAS systems are relevant to households wanting central local storage, scheduled backup tasks and multi-version copies from several devices.

  • Synology backup tools can copy NAS data to USB storage, another destination or cloud services.
  • Synology recommends a 3-2-1 approach and notes that RAID and drive failure can still lead to data loss. A NAS or mirrored disks alone are not a complete backup plan.

Frequently asked questions

Is one external drive kept beside the computer enough for household backup?

No. It is a separate copy only while it remains usable and separate from the original device, but it can still be lost, stolen, damaged with the computer or exposed when permanently connected during malware or ransomware activity. The National Cyber Security Centre advises keeping a removable backup separate and adding an off-site or cloud copy for files that cannot be replaced.

How should a household choose storage capacity?

Measure the files that must be protected across every phone, tablet and computer, including photos, videos, documents and any required device backup. Choose capacity or a subscription allowance above the current total with room for future media, rather than assuming included free cloud storage covers everything important.

Does photo sync count as a backup?

It can protect photos from the loss of one device, but check the provider’s separate sync, backup, deletion and version-recovery rules. Apple states that iCloud Photos is synchronised separately from daily iCloud Backup, with changes reflected across devices using iCloud Photos.

What should be checked before relying on Android backup?

Confirm the selected account, whether photos, videos and device data are enabled, whether the latest backup completed and whether important apps support backup and restore. Google states that restoration varies by device and Android version and that not every app can back up or restore all data.

Is RAID in a NAS the same as backup?

No. RAID or another local NAS copy may help with some drive failures, but it does not create an off-site recovery copy or remove the risk of NAS or drive failure. Synology recommends copies on different media with one off-site copy, and advises backing NAS data up to another destination.
