SCHEDULE YOUR DSpace 9 BACKUP on UBUNTU

-----------------------------------------------------------------------------------------------------------------------------

Step 1: Create Backup Script

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

---------------------------------copy text--------------------------------------

#!/bin/bash

# Date

DATE=$(date +%F)

# Paths (CHANGE if needed)

DSPACE_DIR=/dspace

BACKUP_DIR=/backup/dspace/$DATE

DB_NAME=dspace

DB_USER=postgres

# Create backup folder

mkdir -p $BACKUP_DIR

echo "Starting DSpace backup: $DATE"

# 1. Database Backup

sudo -u postgres pg_dump -Fc $DB_NAME > $BACKUP_DIR/dspace_db.dump

# 2. Assetstore Backup

tar -czf $BACKUP_DIR/assetstore.tar.gz $DSPACE_DIR/assetstore

# 3. Config Backup

tar -czf $BACKUP_DIR/config.tar.gz $DSPACE_DIR/config

# 4. Themes (optional but recommended)

tar -czf $BACKUP_DIR/themes.tar.gz $DSPACE_DIR/webapps

# 5. Cleanup old backups (keep last 7 days)

find /backup/dspace/* -maxdepth 0 -type d -mtime +7 -exec rm -rf {} \;

echo "DSpace backup completed successfully"

---------------------------------copy text---------------------------------

Step 2: Make Script Executable

sudo chmod +x /usr/local/bin/dspace_backup.sh

Test manually:

sudo /usr/local/bin/dspace_backup.sh

Step 3: Schedule Backup using CRON

sudo crontab -e

0 2 * * * /usr/local/bin/dspace_backup.sh >> /var/log/dspace_backup.log 2>&1

(This will schedule a daily backup at 2:00 AM)
