And yet, this gluing together of terms like login, logon, backup, and setup as verbs is common, especially in writing about computers. Not for everyone, however. Some well-known software companies, for example, carefully maintain the distinction in their programs and documentation.
But habits are difficult to change. Those who react to the one-word verb as an error will probably have to get used to it, and those who use the one-word verb will have to recognize that others will see it and wince.

Word Origin for log
- short for logarithm
unshaped large piece of tree, early 14c., of unknown origin. Old Norse had lag "felled tree" (from stem of liggja "to lie"), but on phonological grounds many etymologists deny that this is the root of English log. Instead, they suggest an independent formation meant to "express the notion of something massive by a word of appropriate sound." OED compares clog (n.) in its original Middle English sense "lump of wood." Log cabin (1770) in American English has been a figure of the honest pioneer since the 1840 presidential campaign of William Henry Harrison. Falling off a log as a type of something easy to do is from 1839.
"record of observations, readings, etc.," 1842, sailor's shortening of log-book "daily record of a ship's speed, progress, etc." (1670s), from log (n.1) which is so called because a wooden float at the end of a line was cast out to measure a ship's speed. General sense by 1913.
in the computer sense, as one word, by 1983, from log in.
- A logarithm.
Also, log on. Enter into a computer the information needed to begin a session, as in I logged in at two o'clock, or There's no record of your logging on today. These expressions refer especially to large systems shared by numerous individuals, who need to enter a username or password before executing a program. The antonyms are log off and log out, meaning “to end a computer session.” All these expressions derive from the use of log in the nautical sense of entering information about a ship in a journal called a log book. [c. 1960]

- easy as pie (rolling off a log)
