This migration utility make one large backup with all files inside directories:

/var/lib/mysql
/var/opt/
/var/www/
/etc/hspc
/etc/hspcd
/etc/httpd
/etc/my.cnf
/etc/powerdns
/vz/

So there is a way to speed up this utility by checking the above directories for some unnecessary files, usually such files are:

• - old dumps in /var/lib/mysql/
• - aspc database copy in /var/lib/mysql/

But in most cases the hugest folder is /vz/tmplrep/ where rpms are stored. Basically, before the migration you may move all /vz/tmplrep/ folder to new server with scp command , and move it on source off /vz/ folder, for example to /root/tmplrep/ .


Also, you may check estimated time how long backup will be created and how much it will take without stopping PBAS with command:





This will not stop MySQL or PBAS. If it will be finished successfully you may start migration to new server.
