Hi,
Regular backup tool (https://help.smartsheet.com/articles/506499-backing-up-your-data) has severe data shortcoming since it doesn't include links (URLs) to attached external files (GoogleDrive, Evernote, etc.). So, users can't recover their full linked attachment based on Smartsheet backup.
a) The backup documentation (https://help.smartsheet.com/articles/506499-backing-up-your-data) doesn't mention it, as well as the backup UI, what could mislead inexperienced users that all their data is being backed up by Smartsheet, but it isn't.
SUGGESTION: Smartsheet should be more transparent on that, updating the documentation and the backup UI to make it clear to the user.
b) The only attachment included in the backups are those uploaded to Smartsheet cloud. It doesn't make sense to use Smartsheet storage just to have attachments in backups. Smartsheet claims handy connections with other apps, but neglects to backup those connections, which are attached as simple "URLs".
SUGGESTION: Smartsheet should implement a backup including links (URLs) to external connections (simple URLs, GoogleDrive, OneDrive, OneNote, etc.). It follows a short screencast with a simple suggestion that may be easy to implement since it follows the same logics of how comments are added to the backup:
