ATC - atc - backups
A backup of your database is created twice per day.To recover a backup, login to ATC and open the page admin.cgi?id=57
Click the recover button in front of a backup to recover the latest backup.
If the recovery fails for whatever reason, you can manually recover a backup by downloading
the backup from cgi-bin/atc/d/backup, extract it with winrar for example and upload all datafiles that you wish to recover.
