synchronized if the database is to operate correctly, and user data must be consistent with the internal structure and table ownership rights. If files are simply backed up onto disk while the database is open, these files can be restored, but the database system may not be able to use them. It is essential that you understand the restoration and data integrity requirements for all key applications on your system and identify any risks to service provision associated with data corruption. Thus, a comprehensive backup and restore plan should include provision for regular cold and warm dumps of databases to a file system that is regularly backed up. A third requirement for a backup and restore service is flexibility: data should be recorded and compressed on media that can potentially be read on a different machine, using a different operating system. In addition, using alternative media for concurrent backups is also useful for ensuring availability in case of hardware failure of a backup device. For example, you may use a CD-ROM as your main backup device for nightly incremental backups, but you may also decide to use a DDS-3 DAT tape drive to create a full dump of the database on a weekly basis. If your server is affected by a power surge, the DAT drive is damaged, and a replacement will take one week to arrive, you can use the CD-ROM dump as a fallback, even though it may not be completely up-to-date.

Typical backup and restore strategies employ three related methods for recording data to any medium: Full dumps Incremental dumps Snapshots A full dump involves taking a copy of an entire file system, or set of file systems, and copying it to a backup medium. Historically, large file systems take a long time to back up because of slow tape speeds and poor I/O performance, which can be improved by using the incremental method. An incremental dump is an iterative method that involves taking a baseline dump on a regular basis (usually once every week) and then taking another dump of only those files that have changed since the previous full dump. Although this approach may require the maintenance of complex lists of files and file sizes, it reduces the overall time to back up a file system because, on most file systems, only a small proportion of the total number of files changes from week to week. This reduces the overall load on the backup server and improves tape performance by minimizing friction on drive heads. However, using incremental backups can increase the time to restore a system, as up to seven (one for each day of the week) backup tapes must be processed to restore data files fully. Seven tapes are required so that a single tape can be assigned to each day. Therefore, using incremental dumps enables you to strike a balance between convenience and the requirement for a speedy restore in the event of an emergency. Many sites use a

combination of incremental and full daily dumps on multiple media to ensure that full restores can be performed rapidly and to ensure redundant recording of key data. A snapshot is a very fast way to store recovery metadata for a UNIX File System (UFS) on a raw device or within an existing file system. Every time a change is made to data or metadata on the snapped file system, the original data is copied to the snapshot copy before the modification is processed. This means that if you overwrite or delete a file accidentally, you can easily retrieve it from the snapshot; so, a snapshot is more like a backup that occurs in real time. A snapshot is incremental, too, because it only occurs when data changes. Using snapshots for retrieval is much faster than going to backup tapes, because the data is stored on a mounted file system. However, as you can appreciate, if your disk contents change frequently, then a large amount of online storage is required to implement snapshotting. After deciding on an incremental or full dump backup strategy, and appropriate use of snapshots, you need to plan how backups can be integrated into an existing network. There are four possible configurations that can be considered: The simplest approach is to attach a single backup device to each server so that the server acts as its own backup host:

This approach is appealing because it allows data to be backed up and restored using the same device, without any requirement for network connectivity. However, this architecture has poor scaling capacity and does not provide for redundancy through the use of multiple backup devices. This can be rectified by including multiple backup devices for a single host:

The cost of maintaining single or multiple backup devices for each server in an organization can be expensive. To reduce cost, many organizations centralize the management and storage of data for entire departments or sites on a single server. This approach is shown in Figure 17-2.
