  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.

Question Change tmp backup directory

Hi all,

We have just set up a new server with 2 disks: a basic 400G SSD, a classic 6T for a data site (/var/www/vhosts/mydomain.com/data.mydomain.com - currently with 1T of data).

We have scheduled a data backup to a remote S3.
Everything works well except the 1st backup once the data has been migrated which failed because there was not enough disk space. Which is understandable, a minimum of temporary disk space is required so that the backup can be created before being sent to S3.

Can you confirm that the variable to modify is "DUMP_TMP_D" in /etc/psa/psa.conf?
Nothing else?

...
# Backups directory
DUMP_D /var/lib/psa/dumps
# Backups temporary directory. DUMP_TMP_D should not be inside of (or equal to) DUMP_D.
DUMP_TMP_D /tmp
...

Wa have 6T on data domain, so:
DUMP_TMP_D /var/www/vhosts/mydomain.com/data.mydomain.com/backup_server_tmp

Thank you.

Ok.
And using a symlink from /tmp to /var/www/vhosts/mydomain.com/data.mydomain.com/backup_server_tmp
and excluding /var/www/vhosts/mydomain.com/data.mydomain.com/backup_server_tmp from the backup ?

How do I know what minimum disk space is necessary for the backup process to be carried out (for example for 2T)?
On the system disk (400G), i've 200G available.
 
To answer both questions you'll have to test to find out what the result is. It's hard to predict.
 
So

Here is the error message from the saved state (S3 backup):
