I have a issue when i try to do this command included in a crontab
plesk db dump DATABASE_NAME > C:\FULL\PATH\TO\FILE_NAME.sql
when I execute manually the command runs perfect and i can backup all my sql files, but when i use this comend inside a crontab, they create and retund the .sql files empty
Thank you.

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
hai am new to plesk am getting error while am updating plesk
Internal error: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'psa.ServiceInstallations' doesn't exist
how to rectify this error
Hello @santhosh,
This behavior may be caused by several issues:
# 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:

Can i use this to restore a domain that was deleted?
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:
https://support.plesk.com/hc/en-us/articles/115000340534-How-to-create-and-restore-the-backup-for-certain-subscription-domain-
https://docs.plesk.com/en-US/12.5/administrator-guide/advanced-backing-up-and-recovering-websites/restoring-backups.65200/
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.
Hello @Sergio Sanchez,
Thank you for your suggestion.

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?
Hola Gabriel

The following command restores the Plesk psa database from the database dump 'psa_dump.sql' located in the
/rootdirectory:# plesk db < /root/psa_dump.sql
or
plesk db psa < /root/psa_dump.sql
What is the right way ?
Hi mw004,
Thanks for the question.
The right command to restore the psa database from a dump is this one:
# plesk db < /root/psa_dump.sql
Just as the KB articles says.
And if the name of the database is test then it should be:
plesk db test < test_dump.sql
not
plesk db < test_dump.sql
Plesk cuts "_dump.sql" and import the file into the test database ?
mw004,
A database dump contains the name of the database in it, so MySQL knows which database is going to be restored from this dump.
Filename does not play any role.
And if the database is created through mysql cli and not through plesk (and the database is not initialized in plesk ) does this command work? Because if a mysql command is used, the database name must be included. For example:
mysql -uroot -p test < test_dum.sql
or
mysql -u admin -p`cat /etc/psa/.psa.shadow` test < test_dump.sql
