1 Title: rrdcached: added commands to suspend writing to rrd files
9 using these commands, one can backup rrd files in a consistent state.
10 There are four new commands in total, 2 for suspend, 2 for resume,
11 one each applying to individual files (SUSPEND/RESUME) and one each
12 for all files at once (SUSPENDALL/RESUMEALL).
13 Please note that these mechanisms are independent from each other so
14 you can't use RESUMEALL to release files suspended with SUSPEND
