Instant Restore After a Media Failure
[chapter]
2017
Lecture Notes in Computer Science
Preserved Fulltext
This allows hiding log replay within the initial restore of the backup, thus substantially reducing the time and cost of media recovery and, incidentally, rendering incremental backup techniques unnecessary ...
We introduce single-pass restore, a technique in which restoration of all backups and log replay are performed in a single operation. ...
Acknowledgments We thank Pinar Tözün and Ryan Johnson for kindly and generously answering our questions about Shore-MT and Shore-Kits. ...
