There is a way to run the Veritas Java console in MacOSX and manage Veritas Cluster Server from a Mac. I used RPM packages from Red-Hat to create a MacOS compatible Java Console, in the end, everything is Java, and Java is portable between systems.
We will need the Veritas Console RPM package, and the alien software to convert rpm files to tar.gz.
Alien can be downloaded from
http://ftp.de.debian.org/debian/pool/main/a/alien/alien_8.83.tar.gz
Decompress the tar file in a temporary folder Read more...
OSX – Mac
MacOS
Time Machine creates incremental backups of files that can be restored at a later date. It allows the user to restore the whole system or specific files.
You can use a TimeCapsule external WiFi disk, or an USB disks that OSX will format to be used as backup storage.
TimeMachine can work with remote units mounted over network protocols like AFP or SAMBA, but this way is not supported by Apple, but they allow you to do it without support running next command to enable it:
$ sudo defaults write Read more...

To copy the partition table and MBR from a disk to create the same definition of partitions as in other, you have to copy the first 512 blocks from the header of the disks like with the next command to copy it to another disk for mirroring two disks without create the partition in both disks:
# dd if=/dev/sda of=/dev/sdb bs=512 count=1
This is correct for EXACTLY the same partition sizes. In the case you want the MBR only on a drive that has a root partition of a different size then issue the same Read more...
Probably the funniest way of migrating a fully functional system is doing it while the system is up and running. You can migrate a live system to another remotely machine booted with a recovery cd that can be used to do a P2V (Physical to Virtual) or live system migration to other physical one.
To achive a network migration we can use the TCP/IP swiss army knife, NetCat (nc).
First, boot a virtual machine or physical one with a recovery cd (like wifislax), be sure to have a disks with same Read more...
