The procedures in this chapter should be performed only by an authorized administrator.
SYSTEM BACKUP INFORMATION
In order to protect your library data, it is important to perform frequent data backups. Daily backups are recommended to avoid the loss of files on the local hard disk due to disk drive failure, power outage, virus infection, accidental deletion, and other potential network problems.
The Mandarin M5 Library Automation System does not currently provide continuous backup. A backup device, such as a tape backup, should be installed to allow backups. In addition, Mandarin recommends that your server be equipped with an automated backup system that can be used to schedule unattended backups.
BACKUP RECOMMENDATIONS
Mandarin recommends performing a daily backup after closing, and a full backup at the end of the week or before a holiday. In case of a hardware failure, a restore of a full backup followed by a restore of the latest partial backup can be completed. In case of a loss of only M5 data, a restore of the latest partial backup can be completed.
Backups must be performed when no users are logged on the server.
Backup Methods
Two recommended backup methods are as follows:
• Partial backup – Backs up only the data that is critical to daily operation of M5. This entails selecting the specific location where M5 data and PostgreSQL data is stored (the default path is c:\m3 server\registry and c:\Program Files\PostgreSQL\9.4\data\base), and starting the backup. This operation completes within a few minutes, and is a reliable solution for restoring M5 data. This type of backup does not back up the operating system or any other files on the computer. If a server failure occurred and the data on the hard disk was lost, the operating system and all applications would have to be reinstall; M5 would be restored from the latest backup, repairing all data and transactions. This type of backup is typically performed by a network administrator.
• Full backup – Backs up the entire server, including the operating system, users, security, login scripts, applications, and all M5 data. This entails selecting the drive (s) and starting the backup. This operation may take a half hour to several hours to complete. This type of backup is typically performed by a network administrator.
