Snapshots
Snapshots (/backups/snapshots) makes a change reversible.
The two things customers most often break a site with — changing the PHP version and updating a plugin — are both a single click in this panel, and both fail the same way: a white page, no certainty about which change caused it, and a backup from last night that would lose today's work. Taking a snapshot immediately before the change costs seconds and turns that into a button.
A snapshot can cover the whole account or a single site. From the page you can create one, roll back to one, and delete one.
A snapshot is not a backup. Snapshots are local, cheap and short-lived by design: the newest few are kept and the rest are dropped, and they never leave the machine — a disk that dies takes them with it. Keep real backups as well.
The same thing from a terminal:
hitechcloudcli user-snapshot --account <user> --create
hitechcloudcli user-snapshot --account <user> --list
hitechcloudcli user-snapshot --account <user> --restore <id>
hitechcloudcli user-snapshot --account <user> --delete <id>
