The only problem with that solution is that if there are any log entries that are created during the application startup, they'll be lost when you copy the file back on top. You may also want to mv the file from /var/tmp to keep things tidy.
This should keep your last four logs while maintaining the current startup log.

VARNISHHIST(1)VARNISHHIST(1)NAME
varnishhist - Varnish request histogram
SYNOPSIS
varnishhist [-b] [-C] [-c] [-d] [-I regex] [-i tag] [-m tag:regex ...] [-n varnish_name] [-r file] [-V] [-w delay] [-X regex] [-x tag]
DESCRIPTION
The varnishhist utility reads varnishd(1) shared memory logs and presents a continuously updated histogram show- ing the distribution of
the last N requests by their processing. The value of N and the vertical scale are dis- played in the top left corner. The horizontal
scale is logarithmic. Hits are marked with a pipe character ("|"), and misses are marked with a hash character ("#").
The following options are available:
-b Include log entries which result from communication with a backend server. If neither -b nor -c is specified, varnishhist acts as
if they both were.
-C Ignore case when matching regular expressions.
-c Include log entries which result from communication with a client. If neither -b nor -c is specified, varnishhist acts as if they
both were.
-d Process old log entries on startup. Normally, varnishhist will only process entries which are written to the log after it starts.
-I regex
Include log entries which match the specified regular expression. If neither -I nor -i is specified, all log entries are included.
-i tag Include log entries with the specified tag. If neither -I nor -i is specified, all log entries are included.
-m tag:regex only count transactions where tag matches regex. Multiple
-m options are AND-ed together.
-n Specifies the name of the varnishd instance to get logs from. If -n is not specified, the host name is used.
-r file
Read log entries from file instead of shared memory.
-V Display the version number and exit.
-w delay
Wait at least delay seconds between each update. The default is 1. file instead of displaying them. The file will be overwritten
unless the -a option was specified.
-X regex
Exclude log entries which match the specified regular expression.
-x tag Exclude log entries with the specified tag.
