Backups & restore points · Where backups go
Why are backups to Google Drive, Dropbox or OneDrive slower?
Short answer: Google Drive, Dropbox and OneDrive deliberately throttle large uploads, so backups there are slower. An external SSD is fastest, and bucket storage such as Amazon S3 is the quickest cloud option.
Those services deliberately limit (throttle) large uploads, so a big backup takes noticeably longer there. They work fine as destinations — just slower, especially for the first full backup.
For the fastest results: - An external SSD is quickest of all. - Bucket storage, such as Amazon S3, is the quickest cloud choice.
After the first backup, only changes are uploaded, so day-to-day backups to any of these are usually quick.
