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.

Yes. But ...

DUMP_TMP_D /var/www/vhosts/mydomain.com/data.mydomain.com/backup_server_tmp

having the DUMP_TMP_D path set inside a directory that's part of the backup looks like a recipe for trouble to me.

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.

 

[Kaspar@Plesk]

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):

However, there is disk space available. How to do??

I am not sure. Maybe try to change the DUMP_D value too.
