If you mean there is an incomplete record at the end of the log file, I see that as an inconsequential problem. In my mind, the priorities are 1) the archive is valid, and 2) the log files are not damaged, 3) the process writing to the log files does not get confused. The archive is a backup. If it was needed to be used, having an incomplete record at the tail seems a very minor, if any, problem. No solution here is perfect. I'm just suggesting what seems practical and safe.
Now, if the log file is a binary file, and would be corrupted by an incomplete write, then that's even more reason not to mess with it by trying to move or truncate it.

gzforce
GZFORCE(1) General Commands Manual GZFORCE(1)
NAME
gzforce - force a '.gz' extension on all gzip files
SYNOPSIS
gzforce [ name ... ]
DESCRIPTION
gzforce forces a .gz extension on all gzip files so that gzip will not compress them twice. This can be useful for files with names trun-
cated after a file transfer. On systems with a 14 char limitation on file names, the original name is truncated to make room for the .gz
suffix. For example, 12345678901234 is renamed to 12345678901.gz. A file name such as foo.tgz is left intact.
