I'm being abrasive for being accused of assaulting Commvault. I am basiclly trying to watn others ot the issue. the data was written to tape, but for some odd reason the bug casued Galaxy to prunt the jobs and then reuse the tape immediately, thus the first 70GB of a 500GB data set are gone! Commvault took 4 weeks to determine this and even then bascially said opps, data gone so sorry. We did a face off Net Backup vs. Commvault and at the end of the day Commvault edged out NBU, it was not forced. The reason the thread lack meaningful info is we have been fighting with Commvault to get the details. I only last week found out the bug was in 5.9 since day one, they have danced around prociding any meaningful info. They tried to blame us for not applying fixes, which we do regularly, and we lost the data in October 2005 and they say Critical Update524 was released on Nov. 7th, 2005 to fix this issue, so tell me how that is our issue. It took them 2 weks just to esclate the problem to engineering. In the end you can think what you wnat, I posted a quick blurb to warn peopel that this product can loose data form a bug that exisited for a long time. We trip over their bugs almost monthly and they basically dance arounds them with manual workarounds and to priority to fixing them. IF you call in with a LOST DATA buig and are a Data Protection company you should take it very seriously and they did not, even when escalated. Also Media Explorer while a nice saftey net is cumbersome, you have to do a full restore, in this case 400GB of the remaining data which is not a quick restore. And while you question my motives it appears digital logged in just to respond to this thread. i have provied information, and sure others have different expieriences, but in all the time we used BE and NSE we never lost a byte, twice in 18 months on Commvault we have lost data, and I mean lost, either never on the tape or rewritten by Galaxy, both time due to bugs.
