Or if you really want to use compress, just use -c and then redirect to a file.... you're still left with the original so it's not actually "moving" the file.
Code:
$ compress -c svm_1.log > /var/tmp/svm_1.log.Z
$ file /var/tmp/svm_1.log.Z
/var/tmp/svm_1.log.Z:   compressed data block compressed 16 bits
$ uncompress -c /var/tmp/svm_1.log.Z > /tmp/uncompressed_log
$ file /tmp/uncompressed_log
/tmp/uncompressed_log:  ascii text

Cheers
