However, existing methods of fault tolerance have problems that they have a large run-time overhead or a dedicated hardware. We propose a method to recover from OS failures that preserves processes and file caches. This method runs two OSes and configures them as an active-backup structure in one computer. By obtaining data after a crash, the active OS does not have run-time overhead to backup a process execution status and file cache data. In addition, the resources consumed to build the active-backup structure are only one CPU core and a small amount of memory. In the implementation, we confirmed that recovery time when using the proposed method is about 0.4 seconds at a minimum and up to about 10 seconds even if 2GB memory is restored. The downtime was up to about 1.5 seconds when the active OS of the proposed system crashed while running a text editor, an NFS server, a database server, and an HTTP server.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"24","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌コンピューティングシステム（ACS）"}],"bibliographicPageStart":"11","bibliographicIssueDates":{"bibliographicIssueDate":"2014-05-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"7"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:46:49.137225+00:00","id":101171,"links":{}}
