SymptomsI have started backup creation via Acronis True Image Server through Parallels Plesk Panel:
System -> Modules -> Acronis True Image Server Management -> Backup now
Selected several partitions to dump, put "Path to storage" and "Backup file name".
However then the backing up process is finished the backup file does not exist.
CauseThe problem was caused by incorrect work of utility atismodbackupmng that starts the dumping.
When the utility becomes daemon it does not create new process group. As result when PHP scripts finish the work all the processes receive SIGTERM and the utility quits.
ResolutionThe problem will be fixed in future update of Parallels Plesk Panel that is going to be released after version 9.2.
Hotfix for Parallels Plesk Panel Unix version 9.0 is attached.
To install it you should replace existent file $PRODUCT_ROOT_D/admin/sbin/modules/atism/atismodbackupmng with attached one and correct owner and permissions, it should be root:psaadm, 755. You may correct permissions with commands chown and chmod:
~# chown root:psaadm /usr/local/psa/admin/sbin/modules/atism/atismodbackupmng
~# chmod 755 /usr/local/psa/admin/sbin/modules/atism/atismodbackupmng
Please remember to backup old file.
IMPORTANT: Do not modify the script. Corrupted script may cause inaccessibility of Parallels Plesk Panel. After the script is installed verify it has correct md5 sum.
Check md5 sum with command md5sum on RedHat-like operating systems, Debian or Ubuntu and md5 on FreeBSD.
~# md5sum atismodbackupmng
