Well users mostly ask this question if they go above the quota and there is no files that they can delete without breaking site..so in their case backup generation of any kind is not option since all backup generation files should be stored in user home directory and control panels or scripts like softaculous can't make backups..even if backup it self will be stored externaly it first have to be generated inside user home directory than copied...I have done these migration few times for users...
And few times I found out that user had backups..just old and since it was placed in home directory deleting it I made some room for new one..and i could use cpanel/plesk migrating tool(depending which hosting package user buy) BUT in some cases there was no work around ...it had to be done via FTP,SCP,rSync..etc and in all cases FTP was our tool to use.
Now I don't know is this the case here ...these are just some situation when users could find themself in situation without any option to generate backup file/s....
But when this happen they should check HOME,Above HTTDOCS,Above WWW or how it is named(this directory is one level higher than domain root directory like public_html ,httdocs,www)and look for old archive backups and also check is trash directory empty....if they have old backup than deleting it they can make room for new one
