sql server - Optimized Way of Scheduling a Differential Backup -


i working data warehouse sql server 2012 , wondering optimized, automated procedure backup/restore strategy.

current observations , limitations:

1) cannot use transaction logs affect load performance - datasets potentially huge large transactions

2) current plan full backup every week , differential backup every day

i not sure when dml operations happen depends on application's usage, there way track number of changes database trigger differential backup? way not affect performance? not want taking unnecessary differential backups.

would change tracking solution scenario? or there overhead involved? not need know actual data changed, fact changed amount.

thanks in advance!

well, there's ( http://www.sqlskills.com/blogs/paul/new-script-how-much-of-the-database-has-changed-since-the-last-full-backup/ ). i'm trying figure out problem you're trying solve. is, if find size below threshold, (by definition) cheap do.

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
