Selecting the Type of Backup Operation n Some backup types use backup markers, which Selecting the Type of Backup Operation n Some backup types use backup markers, which are also known as archive attributes. n n n When a file changes, an attribute is set on the file that indicates the file has changed since the last backup. When you back up the file, this clears or resets the attribute. There are five types of backups: normal, copy, incremental, differential, and daily. 6

Considerations for Combining Backup Types n n An effective backup strategy combines different backup Considerations for Combining Backup Types n n An effective backup strategy combines different backup types. Some backup types require more time to back up data but less time to restore data. Some backup types require less time to back up data but more time to restore data. If you combine backup types, markers are critical. Both incremental and differential backups check for and rely on markers. 7

Example: Combining Normal and Differential Backups n n On Monday, perform a normal backup. Example: Combining Normal and Differential Backups n n On Monday, perform a normal backup. On Tuesday through Friday, perform differential backups. Differential backups do not clear markers, so all backups include all changes since Monday. This strategy takes more time to back up but less time to restore. 8

Example: Combining Normal and Incremental Backups n n On Monday, perform a normal backup. Example: Combining Normal and Incremental Backups n n On Monday, perform a normal backup. On Tuesday through Friday, perform incremental backups. Incremental backups clear markers, so each backup includes changes since the previous backup only. This strategy takes less time to back up but more time to restore. 9

Example: Combining Normal, Differential, and Copy Backups n n n On Monday, perform a Example: Combining Normal, Differential, and Copy Backups n n n On Monday, perform a normal backup. On Tuesday, perform a differential backup. On Wednesday, perform a copy backup, which n n n Includes all selected files Does not clear markers or interrupt the usual backup schedule Creates a snapshot of your data On Thursday and Friday, perform differential backups.
