The mechanics of how to backup photos on Android take four taps. The conditions attached to them take longer, and they are the part that decides whether the arrangement holds up over years rather than weeks.
Four taps, and one condition Google states before any of them: backup goes to one account.Turning it on
Everything after that is about where the photographs land, and the first thing to know is that the destination is not a photo service with its own space. Google states it plainly: your account storage “is shared across multiple products like Google Photos, Google Drive, and Gmail”. A large mailbox and a large photo library are competing for the same allowance, and each account comes with up to 15 GB of it.
Original quality
nothing is changed
Storage saver
smaller, and it shows
The choice between those two used to be the choice between free and paid. It is not any more, and the date is published.
That date is the hinge, and it explains a confusion this page exists partly to clear up.
Storage saver used to be free and unlimited; it is neither now. What was uploaded under
the old arrangement stays outside the count for ever, which is why a library that has been
running for a decade can look enormous and still fit. Anything added after that date counts —
both settings count — and the only difference between them is how much of the allowance
each photograph spends.“Any photos or videos you backed up in High quality, now called Storage saver,
before June 1, 2021 don’t count toward your Google Account storage.”
So the practical reading of the two options today is simpler than the old advice suggests. Storage saver buys you more photographs per gigabyte, not free ones — and it buys them by resizing anything over 16 MP, possibly changing the file format, and bringing video down to 1080p. Original quality spends the allowance faster and changes nothing. Neither is a trick; the trade is stated in both directions.
Google publishes the numbers, and they are worth knowing before a large file fails quietly.What will and will not go up
Google marks that one Important and puts it above the quality options rather than in a
footnote. It is worth reading slowly, because it describes the one failure mode a backup is
supposed to be immune to: doing nothing. An archive you never open is exactly the sort
of archive people believe they have made, and this is the published condition attached to it.
The page linked from that sentence sets out the inactivity policy in full.“If you’re inactive in Google Photos for 2 years or more, your content may be
deleted.”
How to know whether it actually worked. Google publishes five statuses that appear at the top of the library, and they are the honest answer to “is it done”: No backup, Preparing backup, Backing up photos, Backup complete, and Backup paused. Tapping the status tells you more. For a single photograph, tap it, then More → About, and scroll to Details — a backed-up item shows its status and size beneath Backed up. And if you meet the badge reading “Not enough storage to back up”, the problem is the shared 15 GB rather than anything to do with the photograph.
One thing this page will not do is tell you Google Photos is a backup in the sense that a second copy on a drive is. It is a copy held by somebody else under published conditions — a shared allowance, a size limit, a format that may change, and a two-year clock. Those conditions are all reasonable and all documented; the point of listing them together is that they are rarely listed together.
And it will not recommend a third-party backup app. The one described here is the one already on the phone, and it is the one Google documents.
The floors below take it three ways: the same job on the other phone, what happens to the allowance the photographs are spending, and getting a copy somewhere you control.
Three ways in. If storage is already full, take the second.
Four taps, one account at a time, and five published statuses that tell you whether it finished rather than whether it started.
Fifteen gigabytes shared with Drive and Gmail, two quality settings that both count against it, and one date that decides what is exempt.
A copy held by somebody else under published conditions is not the same as a copy on a drive in a drawer. Both are worth having.
It will not tell you which quality setting to pick. That depends on how many photographs you take and how large they are, and Google publishes enough for you to work it out in a minute.
It will not recommend a third-party backup app. The documented one is already installed.
And it will not call this a complete backup strategy. It is one copy, held under conditions that are published and worth reading — which is a good thing to have and not the only thing. What holds instead is simple: the four-tap route through Photos settings and Backup, the statement that backup goes to only one Google Account at a time, the note that Google Account storage is shared across Google Photos, Google Drive and Gmail with up to 15 GB per account, the size and format limits, the descriptions of Original quality and Storage saver and what each changes, the note that photos backed up in High quality before 1 June 2021 do not count toward storage, the warning that content may be deleted after two years of inactivity, and the five backup statuses are quoted from Google’s Photos Help pages listed below.
