Backing up/restoring a database in Plesk for Linux

Creating a database dump

# plesk db dump <database_name> > /path/to/<dump_name>.sql

Example
The following command creates a database dump of the Plesk 'psa' database in the /root directory with today's timestamp:

# plesk db dump psa > /root/psa_dump.sql

The following database dump will be created:

# ls /root/psa_dump.sql
psa_dump.sql
Restoring a database from a database dump

# plesk db < /path/to/<dump_name>.sql

Example
The following command restores the Plesk psa database from the database dump 'psa_dump.sql' located in the /root directory:

# plesk db < /root/psa_dump.sql

Backing up/restoring a database in Plesk for Windows Server

Creating a database dump

Example
The following command creates a database dump of the Plesk 'psa' database on C:\ drive:

C:\> plesk db dump psa > C:\psa_dump.sql
Restoring a database from a database dump

Use this command:

C:\> plesk db < C:/path/to/<dump_name>.sql

C:\> plesk db < C:\psa_dump.sql

@Alex Rubio Cazador
Try using the full path to the executable instead of the alias:

For Linux:

# MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysqldump -u admin DATABASE_NAME > /full/path/to/BACKUP_FILE_NAME.sql

For Windows Server:

C:\>"%plesk_dir%\Mysql\bin\mysqldump.exe" -uadmin -p<plesk_admin_password> -P8306 DATABASE_NAME > C:\FULL\PATH\TO\FILE_NAME.sql

Hello @santhosh,

This behavior may be caused by several issues:
- Server is running out of RAM.
- Some limits are exceeded on a container or on a hardware node.
1. Connect to the server via SSH;
2. Make sure that it is enough memory or container resources:
  # free -m
  # cat /proc/user_beancounters
  
  There should be enough memory and all 'failcnt' values should be 0.
  
  Do the following in order to fix the issue:
  
  If you are leasing a virtual container, please contact your service provider in order to increase container limits.
  
  Increase amount of RAM or SWAP on the server.
3. After fixing the limits issue, re-run the upgrade How to upgrade Plesk to the next release

Hello @iamkingsleyf,

For restoring whole domain (subscription) it is required to use the backup, created by backup manager.
Navigate Tools & Settings > Backup Manager > select required backup and choose the subscription you need to restore.

Use the following articles as reference:

Please note that ...
plesk db dump <database_name> > /path/to/<dump_name>.sql
... and the respective ...
MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysqldump -uadmin <database_name> > /path/to/<dump_name>.sql
.. as well as the backups generated in the backup manager (I assume the same tools are used) will not backup created events.

To include events use
MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysqldump -uadmin <database_name> --events > /path/to/<dump_name>.sql

Would be nice to see this added to the the backup manager as I was quite astonished to see that my database backups do not contain events.

Tengo problemas con el volumen de copias de seguridad que genera y me quedo sin memoria. Como configuro para que solo se deje la ultima copia de seguridad y no se acumulen las antiguas?
