diamond187 Posted November 16, 2009 Report Share Posted November 16, 2009 Have a strange problem that suddenly cropped up on one of my exchange server database backups: (FYI, it's disk to disk to help any confusion) The backup set consists of two members, 1-Exchange and 2-Exchange, as at the time I didn't know sets could be grown if no backup was currently being done it it (duh!). Either way, total size for 1-Exchange is 298.0G, 2-Exchange has 806.0G. total space on the destination disk is about 1.5Tb, so it's not a matter of overextending. Summary shows a current use of 397.2G, which of course should very easily fit into the 1Tb(ish) space allocated, but both show "zero K 0%" free. I've grown the first set to 500Gb netting me 203Gb to play with and to stem the problem of backups not occuring, but this brings up a larger issue of why this has happened and how we can avoid it happening again. Anyone have any ideas? Is this a 'real' issue, or another case of user-being-stupid? Any help would be appreciated! Diamond187 Quote Link to comment Share on other sites More sharing options...
Mayoff Posted November 16, 2009 Report Share Posted November 16, 2009 Check the member properties to make sure the "use at most" value is set to 99% and that the member is not marked as skip or missing. Quote Link to comment Share on other sites More sharing options...
diamond187 Posted November 16, 2009 Author Report Share Posted November 16, 2009 Well, increasing that to 99% did increase my free space to around what is overall free on the disk it is backup up to; however, why would that be... Is shows "Use at most XXG *or* XX percent"? Setting it to say, 10% of 2.5Tb should use 250Gb (making this up for easier math), so if you have a 150G backup set you should still have 100G left, right? That is assuming that percent is 'percent of total space' and not 'percent of free space' that is - Is that assumption correct? Quote Link to comment Share on other sites More sharing options...
