26 I was thinking a journaling file system would be best. I was even
27 curious about ext4. I have not used ext4 yet but giving ot some
28 thought. May try that on my brothers and see how it does.

30 He is currently using windoze XP. I can't count the number of times the
31 power has went off. I been telling him for years that he is just plain
32 asking for it. He is one of those, if it works, don't change anything
33 to make it better types. So, when something blows up, he will have a
34 healthy dose of regret and 20/20 hindsight too.

36 I have a older CyberPower 1250AVR myself and it works OK. I have yet to
37 get nut configured properly tho. I installed the same version and
38 copied the config files from my old rig over, it just fills up messages
39 with errors and such. That may be another thread one day. I like the
40 CyberPower UPS's too. I put in new batteries a couple years ago for mine.

42 We live on the end of the line so we do have spikes, surges and all
43 that. I checked on the internals of my UPS and it has a healthy set of
44 MOV's in there. I was glad to see that. I think that is one reason my
45 old rig has lasted so long.

47 Thanks for the info.
