Summary

This chapter covered principles and concepts needed to effectively design and implement a backup strategy for your local computer or your network. First, you learned about backing up file systems, including backup planning, details about incremental backups, and the ufsdump command. Then, you read about a new standard feature of Solaris 9, UFS snapshots, taken with the fssnap command. UFS snapshots enable you to back up a file system without unmounting it first.

Next, you learned how to restore backups with the ufsrestore command. A variety of restoration types were covered, including special case restorations of an entire file system, as well as the root (/) and /usr file systems.

Finally, this chapter concluded with an examination of other helpful copy and backup utilities. Commands covered were dd, cpio, tar, and pax.
