REXE Technology backup options: automatic snapshots, manual backups, and application-level backup strategies. Learn how to prevent data loss and recover quickly from any incident.
Data loss is one of the most critical issues in server management. Hardware failure, software bugs, accidental deletion, or cyber attacks can all lead to data loss.
REXE Technology offers various backup options to keep your data safe.
Backup is the most important part of server management. Using a server without regular backups carries significant risk.
Automatic snapshots take a full disk image of your server at regular intervals.
| Feature | Value |
|---|---|
| Frequency | Daily |
| Retention | Last 3-7 snapshots |
| Timing | Night hours (low traffic) |
| Restore | One-click via panel |
| Cost | Optional add-on |
Automatic Snapshot Flow:
03:00 AM → Snapshot starts
→ Disk image is taken
→ Previous snapshots enter rotation
→ Oldest snapshot deleted (FIFO)
Automatic snapshot is the easiest and most reliable backup method. It can be activated during or after server ordering.
Take manual snapshots anytime through the customer panel.
Use Cases:
Manual Snapshot Steps:
1. my.rexe.tr → My Services → Server Management
2. Click the "Take Snapshot" button
3. Enter snapshot description (e.g. "Before Nginx update")
4. Confirm → Snapshot is created
When taking a manual snapshot, ensure the server is not performing intensive I/O operations. For database servers, it is recommended to flush the database before taking a snapshot.
In addition to server snapshots, application-level backups are recommended:
# MySQL / MariaDB
mysqldump -u root -p --all-databases > /backup/db_$(date +%Y%m%d).sql
# PostgreSQL
pg_dumpall -U postgres > /backup/pg_$(date +%Y%m%d).sql
# MongoDB
mongodump --out /backup/mongo_$(date +%Y%m%d)/
# Compress and backup a specific directory
tar -czf /backup/web_$(date +%Y%m%d).tar.gz /var/www/
# Backup to remote server via rsync
rsync -avz /var/www/ user@backup-server:/backup/web/
#!/bin/bash
# /root/backup.sh
DATE=$(date +%Y%m%d_%H%M)
BACKUP_DIR="/backup/$DATE"
mkdir -p $BACKUP_DIR
# Backup database
mysqldump -u root --all-databases > $BACKUP_DIR/db.sql
# Backup web files
tar -czf $BACKUP_DIR/web.tar.gz /var/www/
# Delete backups older than 7 days
find /backup -maxdepth 1 -type d -mtime +7 -exec rm -rf {} \;
echo "Backup completed: $BACKUP_DIR"
Automatic execution via cron:
# Backup every night at 02:00
0 2 * * * /root/backup.sh >> /var/log/backup.log 2>&1
| Use Case | Recommended Plan |
|---|---|
| Personal website | Weekly automatic snapshot |
| E-commerce site | Daily snapshot + daily DB backup |
| Game server | Daily snapshot + game data backup |
| Enterprise app | Daily snapshot + hourly DB backup + remote backup |
| Database server | Daily snapshot + hourly incremental backup |
Snapshot restore completely replaces the server's current state. All changes after the snapshot date will be lost.
# MySQL restore
mysql -u root -p < /backup/db_20240101.sql
# File restore
tar -xzf /backup/web_20240101.tar.gz -C /
Making backups isn't enough — regularly test restoring them to ensure they work.
Yes, automatic daily snapshot backup service is offered as an optional add-on. It can be activated during or after server ordering.
Go to the Snapshots section in the customer panel (my.rexe.tr) and restore any snapshot with one click.
A snapshot takes a full disk image of the entire server and enables complete system recovery. Application-level backup only backs up specific databases or files — it's faster and uses less storage, but only restores the specific application, not the entire server.
