crontab -e (crontab -l for a list of jobs)

On HP1,2,6,11, add line (to activate WOL):

@reboot (sleep 60 && echo "ondemand" | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor)

On Macs, Add line:

@reboot setpci -s 0:1f.0 0xa4.b=0

10. Rsync HP1Docker Paperless > UNAS-Pro (with smb verification, folder protection, one way every hour)#

Add control file at destination:

echo "DO NOT DELETE — rsync safety canary for Paperless mirror" \
  > /mnt/Documents/.paperless-canary
chmod 444 /mnt/Documents/.paperless-canary
mkdir -p /home/marc/docker-compose/paperless/scripts/
nano /home/marc/docker-compose/paperless/scripts/paperless-sync.sh

Script Content (paperless-sync.sh):

#!/bin/bash

LOG="/home/marc/docker-compose/paperless/logs/Rsync$(date '+%Y-%m-%d %Hh%M') Paperless-Rsync-cronjob.log"

echo "=== $(date) Starting Paperless sync ===" | tee -a "$LOG"

mountpoint -q /mnt/Documents && \
findmnt -n -t cifs /mnt/Documents >/dev/null 2>&1 && \
[ -f /mnt/Documents/.paperless-canary ] && \
rsync -avh --delete --progress --stats /mnt/paperless/media/documents/originals/ /mnt/Documents/Paperless/ | tee -a "$LOG"

echo "=== $(date) Sync completed ===" | tee -a "$LOG"

# Delete old logs
find /home/marc/docker-compose/paperless/logs/ -type f -name '*Paperless-Rsync-cronjob.log' -mtime +7 -delete

Make executable and add to crontab:

chmod +x /home/marc/docker-compose/paperless/scripts/paperless-sync.sh
crontab -e
0 * * * * /home/marc/docker-compose/paperless/scripts/paperless-sync.sh

Setup logs and logrotate:

mkdir -p /home/marc/docker-compose/paperless/logs && chown marc:marc /home/marc/docker-compose/paperless/logs/
nano /etc/logrotate.d/paperless-rsync

Logrotate config:

/home/marc/docker-compose/paperless/logs/*.log {
    daily
    rotate 7
    missingok
    notifempty
    copytruncate
}

Manual log purge: logrotate -f /etc/logrotate.d/paperless-rsync

Manual dry run: ```bash LOG="/home/marc/docker-compose/paperless/logs/Rsync/$(date ‘+%Y-%m-%d %Hh%M’) Paperless-Rsync-cronjob-dryrun.log" &&
mountpoint -q /mnt/Documents &&
findmnt -n -t cifs /mnt/Documents >/dev/null 2>&1 &&
[ -f /mnt/Documents/.paperless-canary ] &&
rsync -avh –delete –dry-run /mnt/paperless/media/documents/originals/ /mnt/Documents/Paperless/ » “$LOG” 2>&1


**Check what needs to be synced:**
```bash
echo "=== Dry-run rsync check ===" && \
rsync -avhn --delete -i /mnt/paperless/media/documents/originals/ /mnt/Documents/Paperless/ && \
echo "=== Diff check ===" && \
diff -r /mnt/paperless/media/documents/originals/ /mnt/Documents/Paperless/ && \
echo "=== File counts ===" && \
echo "Source:" $(find /mnt/paperless/media/documents/originals/ | wc -l) "files" && \
echo "Destination:" $(find /mnt/Documents/Paperless/ | wc -l) "files"

Manual sync:

LOG="/home/marc/docker-compose/paperless/logs/Rsync/$(date '+%Y-%m-%d %Hh%M') Paperless-Rsync-cronjob.log"
echo "=== $(date) Starting Paperless sync ===" | tee -a "$LOG"
mountpoint -q /mnt/Documents && \
findmnt -n -t cifs /mnt/Documents >/dev/null 2>&1 && \
[ -f /mnt/Documents/.paperless-canary ] && \
rsync -avh --delete --progress --stats /mnt/paperless/media/documents/originals/ /mnt/Documents/Paperless/ | tee -a "$LOG"
echo "=== $(date) Sync completed ===" | tee -a "$LOG"

Check logs:

tail -n 50 "/home/marc/docker-compose/paperless/logs/$(date '+%Y-%m-%d %Hh%M') Paperless-Rsync-cronjob.log"
