1) Auto Back လုပ်မယ့် vps မှာ Source folder တွေရှိ/မရှိ စစ်

ls -la /opt/marzban /var/lib/marzban

Backup မလုပ်ခင် လိုအပ်သော host setting inbound tamplates အားလုံးကို လိုအပ်သလို အရင် ပြင်ဆင်ထားပါ

2) rclone + Google Drive remote ချိတ်

2.1 rclone install

sudo apt update
sudo apt install -y rclone

2.2 rclone config (Interactive)

pc မှာဆိုရင် reclone application ဒေါင်းထားဖို့ လိုအပ်ပါတယ်

.\rclone.exe authorize "drive" "eyJzY29wZSI6ImRyaXZlIn0"

Option config_token.
Execute the following on the machine with the web browser:
        rclone authorize "drive" "eyJzY29wZSI6ImRyaXZlIn0"
Then paste the result.
Enter a value.

2.3 Drive ချိတ်ပြီးပြီလား စမ်း

rclone lsd gdrive:

3) Google Drive ထဲ target folder ဆောက်

rclone mkdir "gdrive:marzban"

4) Backup script ရေးပေးထားရပါမယ်

Script location: /usr/local/bin/marzban_gdrive_backup.sh

sudo nano /usr/local/bin/marzban_gdrive_backup.sh

အောက်က script ကို အပြည့်အစုံ paste လုပ်ပါ:

#!/usr/bin/env bash
set -euo pipefail

# =========================
# Marzban Backup -> Google Drive
# Drive Structure:
#   gdrive:marzban///
# Local Structure:
#   /opt/backups/marzban///
# Retention:
#   Remote: delete files older than 72h (3 days) (HOST scope only)
#   Local : delete files older than 3 days
# =========================

TS="$(date '+%Y-%m-%d_%H-%M-%S')"
DATE_DIR="$(date '+%Y-%m-%d')"
HOST="$(hostname -s)"

# Source folders
SRC1="/opt/marzban"
SRC2="/var/lib/marzban"

# Local backup base
WORKBASE="/opt/backups/marzban"
WORKDIR="${WORKBASE}/${HOST}/${DATE_DIR}"

# rclone remote + folder
REMOTE="gdrive"
REMOTE_BASE="marzban"
REMOTE_HOST_BASE="${REMOTE_BASE}/${HOST}"
REMOTE_DIR="${REMOTE_HOST_BASE}/${DATE_DIR}"

# Create local workdir
mkdir -p "$WORKDIR"

# Validate sources
for d in "$SRC1" "$SRC2"; do
  if [ ! -d "$d" ]; then
    echo "ERROR: missing folder: $d"
    exit 1
  fi
done

# Archive file name
ARCHIVE="${WORKDIR}/${HOST}_marzban_${TS}.tar.gz"

# Create tarball (absolute paths preserved)
# NOTE: tar paths are relative to /
tar -czf "$ARCHIVE" -C / \
  "opt/marzban" \
  "var/lib/marzban"

# Create checksum (for integrity verification)
sha256sum "$ARCHIVE" > "${ARCHIVE}.sha256"

# Ensure Drive folder exists
rclone mkdir "${REMOTE}:${REMOTE_DIR}"

# Upload archive + checksum
rclone copy "$ARCHIVE" "${REMOTE}:${REMOTE_DIR}" --transfers 2 --checkers 4
rclone copy "${ARCHIVE}.sha256" "${REMOTE}:${REMOTE_DIR}"

# ✅ Remote retention (HOST scope only)
# This prevents VPS A from deleting VPS B backups.
rclone delete "${REMOTE}:${REMOTE_HOST_BASE}" --min-age 72h --drive-use-trash=false
rclone rmdirs "${REMOTE}:${REMOTE_HOST_BASE}" --leave-root

# Local retention: keep only 3 days
find "$WORKBASE" -type f -mtime +3 -name "*_marzban_*" -delete
find "$WORKBASE" -type d -empty -delete

echo "OK: backup uploaded: ${ARCHIVE}"

Permission ပေး:

sudo chmod 700 /usr/local/bin/marzban_gdrive_backup.sh

4.1 manual တစ်ခါ run စမ်း

sudo /usr/local/bin/marzban_gdrive_backup.sh

4.2 Drive ထဲ backup file ရောက်လာလားစစ်ပါ

rclone lsl "gdrive:marzban" | tail -n 20

5) Asia/Yangon timezone ထားပေးပါမယ်

sudo timedatectl set-timezone Asia/Yangon
timedatectl | grep "Time zone"

6) systemd service + timer (Daily 02:00) အလုပ်လုပ်ဖို့ script ထည့်ပါမယ်

6.1 Service file

sudo nano /etc/systemd/system/marzban-gdrive-backup.service

ဒီအတိုင်း paste:

[Unit]
Description=Backup Marzban folders to Google Drive
Wants=network-online.target
After=network-online.target

[Service]
Type=oneshot
ExecStart=/usr/local/bin/marzban_gdrive_backup.sh

6.2 Timer file

sudo nano /etc/systemd/system/marzban-gdrive-backup.timer

ဒီအတိုင်း paste:

[Unit]
Description=Run Marzban backup daily at 02:00

[Timer]
OnCalendar=*-*-* 02:00:00
Persistent=true
RandomizedDelaySec=300

[Install]
WantedBy=timers.target

6.3 Enable + Start

sudo systemctl daemon-reload
sudo systemctl enable --now marzban-gdrive-backup.timer

6.4 Next run / status စစ်

sudo systemctl list-timers --all | grep marzban
systemctl status marzban-gdrive-backup.timer --no-pager

7) Log စစ် (manual run နဲ့ log ပေါ်အောင် စမ်း)

sudo systemctl start marzban-gdrive-backup.service
journalctl -u marzban-gdrive-backup.service -n 80 --no-pager

8) Restore
