9.5.4 was just bugfixes, so I don't see any reason to bypass that one.
Since my plesk servers and mneese77 server has the same issue with automated backup I believe its a new plesk bug.
I am very sure I am not doing something wrong. Have been working the automated backup this way for 2 years now.
And also whenever I have mentioned a bug I have seen it fixed after a few versions even if almost none has mentioned it on the internet.
Whats "weird" is that they seem to fix some issues that have to do with the bandwidth monitoring because isps for sure ask for these bugs to be fixed while other issues which are more important to me like the mail and backup etc are not being fixed for months or years.
The issues with the backups started since 9.2 version and now it has just become worse than fixed !!!
