Visp.net employs powerful and consistent backup routines to keep all data across all servers safe. Our backup schedule adjusts to suit the needs of the servers and customers slightly; however, at the time of this article, the current backup procedure is as follows:
- Email Servers: Backed up weekly, backups held for minimum of 8 weeks.
- Web Servers: Backed up weekly, backups held for minimum of 8 weeks.
- Database Servers: Backed up weekly, backups held for minimum of 8 weeks.
Because we back up often, we can often restore a file, directory, or mail spool for any given time period up to the oldest backup of that particular server. With most services, a complete backup is always available as of the snapshot time the backup was taken. We can restore from any available backup. Email poses special challenges. Because many subscribers use POP3 to check their email, every time they check their email, it downloads all email off the server. Once it's removed from the server, it cannot be backed up, and therefore cannot be restored. Here is an example:
User email@example.com receives an email from an important vendor at 2:00PM Monday, December 22nd. The next backup for this server is scheduled to run Friday evening (4 days later). If Joe checks his email via POP3 and downloads the message to his computer any time between 2:00PM Monday and Friday evening, the file will be deleted from the server and when the backup runs there will be no file to backup. If a request is made to restore this user's mail spool, it is very unlikely they will get many emails restored if they are using POP3 and have checked their email recently.
For users like Joe that want to ensure their email gets backed up, they should use one of the following methods.
- Set their POP3 application to leave messages on the server for 10-14 days.
- Use IMAP instead of POP3.
We do frequent backups for two reasons:
- In the event of a catastrophic hardware failure of the device/server, the data is stored on so we can rebuild the device with all of its original data.
- For accidental deletion or mishandling of files by the ISP, the subscriber, or visp.net.
Backups of data have no cost to ISPs or subscribers. We factor the costs of maintaining the backups into our regular pricing for services. Restoration of data related to a hardware failure at the visp.net NOC or mishandling of files by visp.net staff is not charged. Simply put, if it's our mistake, there will be no charge. Restoration of data related to the ISP or subscriber mishandling or deleting the data does have a restoration cost. This could include accidental deletion of a file or an account. The cost to restore data in this case is a flat fee of $25.00. This assumes the request is to restore the files of X date to their original location, and the process to do so takes our staff less than 30 minutes. If the ISP or your subscriber requests the files be handled differently than a standard restoration, our normal rate of $120/hr will apply. To request restoration of files, please specify the files you wish to have restored and the ideal backup date of the restoration. For instance, if a subscriber deleted some files on accident a week ago, you would want to request a 2 week old backup to get the files prior to the point where they were deleted. Submit this request at http://support.visp.net by placing a trouble ticket with the requested data. During restoration, any files restored will replace the files already on the server. So if file joesfile.txt is asked to be restored, and there is already a joesfile.txt in the restoration directory, it will be automatically overwritten in the restoration process.
