Found that a recent update of our Plesk 9.5.4 server had broken the scheduled backups although manual backups were still working fine. Its seems that after updating PHP to 5.3 and MySQL to version 5.5 the Plesk Backup Manager was erroring
After a recent upgrade to Plesk 9.5 for Linux, I started receiving the following error messages on a daily basis :
/bin/sh: line 1: 2462 Segmentation fault /usr/local/psa/admin/sbin/backupmng> /dev/null 2>&1;
It seems that, when Plesk performs a backup using backupmng utility, there is an error, and you may find errors simliar to below in /var/log/messages log file :
Mar 24 01:33:02 : backupmng: segfault at 0000000000000010 rip 00000039b6a4a855 rsp 00007fff4fa91710 error 4
Resolution – provided by Plesk
Fixed backupmng utility for CentOS 5 and Debian 5 in attached file.
For fix installation replace %plesk_dir%/admin/sbin/backupmng file by file from attach and correct owner and permissions, it should be root:root, 750.
A simple command to ensure permissions are correct; chown and chmod:
chown root:root /usr/local/psa/admin/sbin/backupmng chmod 750 /usr/local/psa/admin/sbin/backupmng
Note: %plesk_dir% is environment variable which points to Plesk installation folder. By default it is /usr/local/psa/
