If your base is missing data, asking yourself the following questions may help in finding out how to retrieve your data.
Do you have any filters that are preventing data from being visible?
Do any of your base snapshots contain the now-deleted data?
Do you have any filters that are preventing data from being visible?
It's entirely possible that your data is still in your base, but just temporarily hidden by filters or in hidden fields.
You may have some filters which are hiding the data you're looking for. If you click on the filters section of the view bar, you can see if filters have been applied.
It is also possible that some of your fields have been hidden. If you click on the filters section of the view bar, you can see in detail which fields have been hidden in the view that you're in.
If you are working with other collaborators who have editor or creator permissions, it is possible that one of them might have deleted the data. If the data you're looking for was deleted in the past seven days, check the trash for your base. If you can find the deleted information, you can restore it there.
You may not be able to find your information in the trash. If so, this could be because the trash was emptied recently by you or one of your fellow collaborators, or because the information you're looking for was deleted more than seven days ago. If you're having trouble tracking down your data, please contact your fellow collaborators and ask if they might have deleted the data or emptied the trash.
Do any of your base snapshots contain the now-deleted data?
If your data has definitely been deleted (and not just hidden through view configuration options, and is not restorable through the trash), you may be able to recover it by restoring one of your base snapshots. For further information on how to restore a base snapshot, please read this article. Please note that workspaces on paid plans have a longer snapshot history.
