There is not enough free disk space on the server to create/restore the backup.
The recommended way is to increase the disk space of the server and resize partitioning.
Warning: Disk partitioning is not covered by Plesk Technical Support. If you are not familiar with Linux system administering and would like Plesk professionals to handle this task, please contact Plesk Professional Services team.
If Plesk server is running in a Virtuozzo container (the file
/proc/user_beancounters exists on the server) the inode limit can be increased as described in the Virtuozzo article. If you are a container owner, contact your service provider for assistance.
If Plesk server is running in a Vultr virtual machine, it is possible to resize the hard disk of the machine using this Vultr article.
Alternatively, try this:
Free up disk space by removing unnecessary files from the server.
Note: In some cases, temporary files can take a significant amount of disk space on the server. Try to remove temporary files according to this KB article.
If possible, attach a Network File System (NFS) and move Plesk data there. Visit these KB articles for details:
