Dated: August 31, 2004
We at JodoHost have decided to implement a new backup strategy to resolve some of the issues in our current backup system. Our current backup system includes a disk redundacy system (via a SCSI RAID1 or RAID5 controller) and data backups to a NAS server
The main issue with these forms of backup is recovery. After a system crash or OS corruption, we have to prepare a fresh system. Recreating the resources of over 1000 sites on a fresh standby server can take a good hour or two and then restoring the data can take another 6 to 8 hours at least (although the entire process is automated).
Through our new backup strategy, we keep a complete mirror of the server's hard disk on a separate SCSI disk which is kept off-site. If a server goes down with a OS or system crash, recovering the server would simply involve swapping the current hard disk with its mirror.
The procedure will be performed every sunday morning between 7:30am to 8:30am. No downtime is expected. The entire procedure will be performed on a live system. The fact that we use high-end systems with hot-swappable disk trays allows us to achieve this. However, the server may (only if needed) to be restarted and if there is a problem (which would be a very rare case), our staff would be on standby to correct it.
This new backup procedure will be started only on Win1, Win4, Win5, Win6 and WinCF to begin with. This new backup strategy will only spamaalalal our existing one, not replace it
