pleskbackup – Unable to parse options

July 31st, 2008 — Linux, Plesk

If you are trying to backup your server to a ftp location don’t forget to specify destination file on the remote server, or you’ll receive this error:

[root@apollo ~]# export FTP_PASSWORD="secret"
[root@apollo ~]# /usr/local/psa/bin/pleskbackup --no-gzip all --skip-logs ftp://backup:@backup.example.com/
Unable to parse options: Bad FTP file format at /usr/local/psa/bin/pleskbackup line 287.

Plesk 8.3.0 extract files from backup

July 17th, 2008 — Linux, Plesk

Extracting files from a Plesk 8.3 backup it’s not an easy task and it’s time consuming.

Let’s examine backup file:

[root@monster ~]# file plesk_bigserver_2008-07-10.backup 
plesk_bigserver_2008-07-10.backup: ASCII English text, with very long lines

Plesk backup is a multi-part mime-encoded file, you can easy restore one domain or whole server using plesk backup utilities, but when you need a few files from backup you’ll need an external tool like ripemime or mpack.

Requirements:

  • Free disk space minimum 2*backup_file_size
  • mpack tool

Check your free space using df(disk free) command.

[root@monster ~]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/hda3             9.2G  2.5G  6.3G  29% /
/dev/hda1             190M   15M  166M   8% /boot
none                 1010M     0 1010M   0% /dev/shm
/dev/hda7              53G   17G   34G  34% /home
/dev/hda6             950M   17M  886M   2% /tmp
/dev/hda5              46G  7.2G   37G  17% /var

Let’s install mpack. On a Redhat/Fedora/CentOS system it’s easy, just subscribe to Dag Wieers’s repository. You’ll need to download rpmforge-release rpm that’s matching your server OS and architecture:

For CentOS 5 and x86_64 architecture we’ll use rpmforge-release-0.3.6-1.el5.rf.i386.rpm:

[root@monster tmp]# wget http://dag.wieers.com/rpm/packages/rpmforge-release/rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm
[...]
[root@monster tmp]# rpm -ivh rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm
http://dag.wieers.com/rpm/packages/rpmforge-release/rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm
[...]
[root@monster tmp]# yum install mpack
[...]

Let’s make a directory where we’ll extract backup files and then extract files there:

[root@monster ~]# mkdir recover
[root@monster ~]# cd recover
[root@monster ~]#  munpack < ../plesk_bigserver_2008-07-15.backup
[...]

Mpack will extract files into separate tar archives where you can locate the domain by archive name and extract files using tar command.
