If you serve numerous websites, you may want to configure the backing up
process so that it does not consume much server resources.
To reduce the server load and set the disk space usage policy:
Go to Tools & Settings > Backup Manager > Settings.
(Optionally) Specify the maximum number of full backups that can be
stored in any type of storage (Maximum number of full backup files
For details, see The Rotation of Scheduled Backup Files below on
Specify the number of simultaneous backup processes in the Maximum
number of simultaneously running scheduled backup processes. The
default value is 10. Type a lesser value.
To make the backup processes release resources to other processes on
the server, select one or both of the following settings:
- Run scheduled backup processes with low priority
- Run all backup processes with low priority
Note that these options increase the backup time. Other server tasks
will not work slower during the backup.
Select the Do not compress backup files checkbox to disable
To prevent the backing up processes from consuming all available disk
space on the server, choose one of the following:
Set Plesk to start a backup only if your server has enough free
disk space to store it. Be aware that this option significantly
increases the backup time as Plesk additionally has to calculate
the size of the future backup.
Note: Plesk for Windows does not directly calculate object sizes but
takes them from the database. As object sizes in the Plesk
database are updated only once a day, the overall calculated
backup size can differ from its real value.
Set Plesk to start a backup only if your server has the specified
amount of free disk space. This option is convenient when you know
the approximate size of the future backup and do not want Plesk to
waste time and resources on calculating it.
Choose whether to allow the use of Plesk server as an FTP storage for
Users can configure their FTP storage to be located on the same Plesk
server where their subscriptions are hosted. If they do so, the
amount of used disk space will double upon creation of each backup.
This can eventually run the server out of free disk space. To prevent
this, we recommend that you clear the checkbox Allow…
