Alternative *nix backup methods

tar cvpzf backup.tgz --exclude=/proc --exclude=/lost+found --exclude=/backup.tgz --exclude=/mnt --exclude=/sys /

Please familiarize yourself with the tar command and its arguments. The man pages are included in the ETM distro.

As noted above, the dd operation for non-RAID configured servers also serves as a full filesystem backup. It can be performed at important milestones to keep the backup current.

Procedure 2. Restoring the complete filesystem, including the OS

Restoring the complete filesystem will depend on how the backup was taken. If it was via the example tar command above, then restoring would involve untarring the backup like so:

cd /

tar xvpfz backup.tgz -C /

NOTE

If restoring a completely destroyed filesystem on the boot partition, the server bootup will have to be done via other media: either a CD/DVD/drive as mentioned at the beginning of this document, or a secondary drive if the system is non-RAID and the secondary drive holds a backup.

If using a dd version of backup to restore from, the dd operation should be performed in the same manner as was done initially, but the "if" and "of" arguments should be reversed. For example:

dd if=/dev/sdb of=/dev/sda bs=100M conv=notrunc,noerror

There are many other methods for backing up and restoring a *nix operating system. Methods include dar, rsync, cp, scp, tar, dd, clonezilla, ghost, amanda, and many more. As mentioned previously, it is expected that a customer's IT organization will have already established backup policies and procedures. If not, or, for general reference, there are many sites available on the internet that discuss this topic. For reference, the following are listed here:

Procedure 3. Backing up the ETM software and data

To backup the ETM software and data, navigate to the Platform->Utilities page, then the AppServer Nodes tab, then select the server you are logged into, right-click, and choose Backup. This will perform a database backup, and then create a tar archive file containing the ETM software, the root directory where ETM is installed, the database backup, and other directories used by ETM, specifically the ftp dir and filestore dir. It will also optionally scp the backup to a remote server if those configuration properties are setup. For convenience, these properties are listed here. They are named as such in the Admin->ETM Config page:

•

Backup Server (ip)
