Error: Insufficient disk space for backup.

[rejith]

Whenever I am trying to take backup through Parallels Plesk (Plesk version:12.0.18 Update #53) getting an error "Error: Insufficient disk space for backup. "

Default backup location is '/var/lib/psa/dumps' with enough space (Near 1TB). Then why showing above error message? Please help me to solve this issue and moreover I am not an advanced linux master.

Version Details:
Version Parallels Plesk v12.0.18_build1200140811.16 os_CentOS 7
OS CentOS Linux 7.1.1503 (Core)

Do you have any cronjobs with build big logs?
How come there is 1 big backup?

Would it be an option to remove that 8GB backup you created and restart with a complete new backup sequence. For example through the Plesk Backup Manager. In Tools & Settings there you can find Backup Manager and if you go to More Settings. There you find Scheduled Backup Settings. There you could setup a "Maximum number of backups in the repository".

Hi Noturns,

I hosted around 12 websites and I took 8gb backup in manual mode 2 weeks back.
I think I dont have any cronjobs running with big logs. How I can trace it?

 

[rejith]

Hi Noturns,

I tried as per the instructions in the above post. But still showing the same error Error: Insufficient disk space for backup.
Is any other way to track this issue?

This would give some insight to the subject matter

Hi Noturns

I checked, nothing special there. I searched for 100MB+ size, results showing only my website files, i uploaded through FTP. So that part is clear. What about any kind of lock files or the old remainings or like that?

 

[rejith]

Here is my error log

I also checked /usr/local/psa/admin/share/pmmcli/pmmcli-rc

and its zero byte. nothing inside!

 

[rejith]

Finally I added
"# Required free disk space (Mb) to perform backup operation
FREE_DISK_SPACE 20"
into /usr/local/psa/admin/share/pmmcli/pmmcli-rc and Backup is running now.

Any one have the latest file backup for /usr/local/psa/admin/share/pmmcli/pmmcli-rc? (CentOS7 with Plesk12)

 

[rejith]

I hope this one will work fine. If any one have Plesk 12 version file of '/usr/local/psa/admin/share/pmmcli/pmmcli-rc', please share.
