# How long does Data Backup keep old versions?

Data Backup keeps a long history but thins it as it ages, so a backup doesn't grow forever: recent versions are kept in full, then one a day, then one a week, then one a month further back.

In practice you can go back to any recent change, to a specific day over the following period, and to a weekly or monthly point beyond that. If something matters at a particular moment — before a big edit, say — press **Back up now** so there's a version from exactly then.
