i forgot about some more things. here i wanna add them.

i always turn of caching on hdd. so my copy and moves are slightly slower, but less chance of corruption due to data loss. also, always copy and delete source. dont move. In linux, they use sync command to flush cache to disk.

good point about filtration there...but you need the kind of uos that supplies from battery even when there is power. naturally they are safer but more costly. But due to more usage, battery lasts for shorter periods of time. you need to change more often. buy i go to electronics market and know people who do repairing jobs. i buy from them and repair myself. comes very cheap. panasonic is a good battery brand. i forgot the name of the best japanese brand though.

dont buy the cheapest ups. buy the online type. and you dont beed 30 min backup. 5 to 10 works for me.

another trick is, attach a wifi router to direct power and set a ping from computer to wifi router ip. also set in script to sync the disk and shutdown when the wifi router is not available for (total backup time - time taken for shutdown) amount of time, that way system will auto shutdown safely even when you are not looking.
