Considering an NFS share is mounted at /nfs_share/, a work space is located at /home/me/workspace/, a directory /nfs_share/backups/ exists, and a file at /nfs_share/backups/ contains the following bash script, the cron job below will use rsync and tar to create a copy of a work space, compress it, and creat daily copies of it in another directory.

#!/usr/bin/env bash
# backup workspace to NFS share
FILE="workspace-$(date +%Y-%m-%d).tar.gz"

# Ensure directories exist
mkdir -p $DEST

# Record start time by epoch second
START=$(date '+%s')

if ! rsync -av --delete $SRC $SYNC ; then
  STATUS="rsync failed"
elif ! tar -czf $FILE $SYNC ; then
  STATUS="tar failed"
elif ! mv $FILE $DEST ; then
  STATUS="mv failed"
  STATUS="success: size=$(stat -c%s $DEST$FILE) duration=$((`date '+%s'` - $START))"

# Log to system log; handle this using syslog(8)
logger -t backup "$STATUS"
echo "$STATUS"

Run it as a cron job at 01:00 by editing sudo crontab -e

# Backup workspace
