Veritas 10/Sony SDX700
Posted on 2006-05-17
In January, I installed a Sony SDX700 tape drive in our Windows 2000 Advanced Server (replacing a old larger tape backup that worked fine). We are using Veritas Version 10 and I have two backup jobs set - one for Mo, Tu, Wed, and Thurs - these are just incremental backups and on Friday night, I run a full backup. I not only backup that server but also an Windows 2003 server - this has a remote license. We are using genuine Sony AIT-3 tapes - 260GB compressed.
On almost a weekly basis, I get the error: Error reading/writing data from/to the media. According to Symantec, this can mean a hundred and one things but here is what I have tried: changing tapes (worked last time but now I have 5 "bad"? tapes); updating drivers; cleaning drive every week; erasing tape; many others. The odd thing is that it first started out with Wednesday but all other days worked; after I put in a new tape; that finally corrected itself in time? - now it has started on Monday's backup; I thought it was fixed after the 2nd new tape I put in because the backup was working but now it has come back again - Monday's backup doesnt work but all the others do. The last time I talked to Symantec, they had nothing else to try other than suggesting I run Sony tape drivers instead of Veritas drivers but I have heard that causes issues - it is writing soft errors to the tape but when I run the diagnostics on the tape drive from Sony, it says it is fine (for whats that worth) - I hate to change the drivers when only one day is the problem.
Has anyone run into this? Thanks.
