backup - How to ensure data consistency across data sources -

-

i have situation have authority data source has service sending data data source across network every time original data source updated. similar offsite backup guess. i'm looking way ensure secondary data source consistent original data source.

i think there atleast 2 different things need check.

  1. data integrity: believe can check checksum style error check.

  2. data reaching it's destination: i'm not sure how can ensure data getting recorded in secondary data source. there possibility data never reaching destination because of network issue or similar.

are there best practices can use ensure secondary data source has data consistency original data source?

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...
