I don't recall seeing upthread mention of the purported BER of LTO tapes: 1 error in 10^18 bits. I wish my experience confirmed this. Recent attempts to restore files (HP tape library, LTO-4, Backup Exec) resulted in a large number of tapes declared un- catalogable. I never recovered the data. I do not believe this reflects the underlying reliability of all tape. I'm a tape believer. But not in the tape systems in my shop. Possible contributing factors: lossy optical fiber links, equipment maintenance issues, unlimited tape lifetimes. YMMV. -- Charles Polisher _______________________________________________ Tech mailing list [email protected] https://lists.lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
