Maintenance is an important part of server management. By making sure that your server's software is up-to-date and free of security issues, you can prevent potential issues with your server.
Backups
It is critical that all important data on your server be backed up in case the worst scenario should occur. You should create a backup prior to any significant change within your applications. In addition, backup maintenance should be done on a regular basis, depending upon how often your content changes. We recommend that you save your backups somewhere other than on the server itself. Reprovisioning a server will wipe out any backups stored on that server. For added security and ease of use, we offer FTP Backup storage space for a fee.
Updates
Server updates and vulnerabilities can be found at any time, causing web-based software to become critically vulnerable. We recommend keeping all services and software up to date with the latest stable version available. Review the documentation provided by your software vendors to ensure that all updates are compatible with your system.
Passwords
Good security includes use of very strong passwords; combinations of upper case and lower case letters along with numbers and special characters. Passwords should be at least 8 characters long and not spell a word found in the dictionary. Passwords should also be changed on a regular basis. Most security experts recommend changing your password every 60 - 90 days.
Anti-Virus
While servers that are not used for Web browsing or personal email use are less vulnerable to viruses, you should still protect your server from these threats. All content should be scanned as it enters the server with an Anti-Virus program. Virtual Private Servers (VPS) require that Anti-Virus programs function without Kernel access.
