admin → backup failed. Not enough disk space to run backup

[Svyatoslav]

Hello I've installed Vesta on cloud server (Ubuntu 14.04 x64),
I've used template "hosting" for domain and all my 5 subdomains,
but everyday Vesta send me a mail:
"admin → backup failed
Not enough disk space to run backup"

Here is "df -h" command results:

Please provide us /var/log/vesta/backup.log. Also how big are all your site together? Do you have a big database?

[Svyatoslav]

My site has 5 subdomains, including 3 forums,
total size of home\admin\web is 2.83Gb
one of these forums has 1.87Gb attachment-data.

I have 3 databases, sizes in .sql-format:
3.828 Mb
0.221 Mb
0.138 Mb

Vesta send me a mail:
"admin → backup failed
Not enough disk space to run backup"

Totaly the same situation. But in my situation it start to appears after moving from one to another server with VestaCP

MY ANSWER:
In the folder /home/backup of my Ubuntu server Vesta try to put .tar archives (about 1.7Gb) every night,
if I delete all existing archives – everything is ok, Vesta put a new archive next night.
So, the problem just because of "not enough disk space".

Decision of the problem:
delete files in /home/backup (after downloading the files to another computer)
and maybe increase hard drive of your server.
