A storage managing unit issues an ID, such as a time stamp number (TS#) next to an immediately previously issued ID to one or more primary storage systems (PDKCs) at regular or irregular intervals. Upon receiving a write command, each PDKC prepares a journal (JNL) including a replica of write data and the newest ID from the storage managing unit, and transmits the journal to a secondary storage system (SDKC). The SDKC stores a received JNL and reflects up to a particular JNL of non-reflected JNLs in a secondary volume. The particular JNL has an ID older by one than the oldest ID of the newest arrival completion IDs in one or more SDKCs."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Computer system and method for performing remote copy using journal","description":"A computer system for performing a remote copy using a journal so as to maintain conformability of data stored in a secondary storage system even though a time stamp is not granted to write data recei","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8539178","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
