Electricity turns off while compressing files

[kj911]

Safer ways use UPS! Electricity off detected, press PAUSE button in last during compression progress paused and hibernate the PC. Electricity its available again, booting PC again, waiting loading all data transferred via to memory from HDD. The PC its fully online, continue data compressing. (Press PAUSE or any buttons in via CMD window.)

Alternatively use DLZ compressor, minimally better CR ratio than LZMA1/2 algos.
