• Alternatively, you can download the latest package from Victoria metrics repository
• Look for package victoria-metrics-linux-amd64-vx.yy.zz.tar.gz

• You need to prepare two file systems:
  • One for hosting database data
  • One for hosting database backups

mkdir /YOUR_FOLDER/victoriametrics
nano /etc/systemd/system/victoriametrics.service

Content victoriametrics.service file :

[Unit]
Description=Victoria Metrics
After=network.target

[Service]
Type=simple
StartLimitBurst=5
StartLimitInterval=0
Restart=on-failure
RestartSec=1
PIDFile=/YOUR_FOLDER/victoriametrics/victoriametrics.pid
ExecStart=/usr/local/bin/victoriametrics -storageDataPath /YOUR_FOLDER/victoriametrics-data -retentionPeriod 6 -graphiteListenAddr=:2003 -dedup.minScrapeInterval=1ms
ExecStop=/bin/kill -s SIGTERM $MAINPID

[Install]
WantedBy=multi-user.target

chmod 755 /etc/systemd/system/victoriametrics.service
mkdir /etc/systemd/system/victoriametrics.service.d
nano /etc/systemd/system/victoriametrics.service.d/ulimit.conf

Create the file ulimit.conf with following content :

[Service]

LimitNPROC=32000

wget https://github.com/VictoriaMetrics/VictoriaMetrics/releases/download/v1.56.0/victoria-metrics-amd64-v1.56.0.tar.gz
tar -zxvf victoria-metrics-amd64-v1.56.0.tar.gz
cp -R victoria-metrics-prod /usr/local/bin/victoriametrics
systemctl enable victoriametrics
firewall-cmd --zone=public --add-port=2003/tcp --permanent
firewall-cmd --reload
systemctl start victoriametrics

• To configure backups, we are going to use victoria metrics vmbackup utility.
• Get the files:

wget https://github.com/VictoriaMetrics/VictoriaMetrics/releases/download/v1.77.2/vmutils-amd64-v1.77.2.tar.gz
tar -zxvf vmutils-amd64-v1.77.2.tar.gz

• Create a script do_vm_backup.sh:

#!/bin/sh
vmbackup-prod -storageDataPath=[VM_DATA_FOLDER] -snapshot.createURL=http://localhost:8428/snapshot/create -dst=fs://[VM_BACKUP_FOLDER]

• Change file permissions

chmod 700 do_vm_backup.sh

• Edit crontab

crontab -e
0 */1 * * * /[PATH_TO_SCRIPT]/do_vm_backup.sh

• The backup will now run once per hour

• To restore a backup, we are going to use the vmrestore utility:

systemctl stop victoriametrics
vmrestore-prod -src=fs:///[PATH_TO_BACKUPS]  -storageDataPath=[VM_DATA_FOLDER]
systemctl start victoriametrics
