SATA RDX backup cartridge report for BackupEDGE   2011 11  2011/11/23 BillMohrhardt
- I have been testing an internal SATA RDX drive, made by Quantum, in an IBM x-series 226 server with dual 3.0 Ghz CPU's, 3 GB of RAM, and dual 73 GB SCSI drives configured as a simple RAID 1. The Operating System is Red Hat Enterprise Linux 5.3, Microlite BackupEDGE version 03.00.03 with the RDX cartridge configured as a file system partition. I modified the retention time to be only 3 days, as I was backing up to the same cartridge, and wanted to verify that the program would automatically delete the oldest archive to make room. When we have a cartridge for each workday, I will extend that back out to 2 weeks. -
Auto Edge archive removal script   2011 09 
- The way I wanted Edge to work, was just like the days when we backed up to Tape. We would pull Master backups each night, label the tapes M-F, and take a SAT tape off-site for an extra layer of protection. When Monday rolled around, the new backup would replace the old Monday backup, rinse, lather, repeat. This changed when we upgraded to Edge 3.x, and started using the NAS. Once we had multiple servers with multiple jobs backing up to the same resource, and not having enough free space on the NAS because backups were piling up, I had to resort to manually deleting things (through edgemenu) on the NAS to free up space. This got old rather quickly, as I had to look down the long list of backup jobs, and determine which ones could be deleted. If I missed one day, the NAS would fill up, and backups would fail. -
Linux|Unix Logical Volume Manager (LVM) on Software RAID   2002 11  2011/01/07 TonyLawrence
- Logical Volume Manager is now included with most Linux distributions. The RedHat 8.0 installer even allows you to create LVM volumes during initial install. LVM offers capabilities previously only found in expensive products like Veritas. If you plan on using LVM, I really recommend doing so on a RAID system, either hardware or software -

Mac OS X dd backup   1997-2004 
- Personally, this makes me a bit nervous. Unflushed disk buffers could mess this up, though apparently he's been ok with it. The system is running while this is dd'ing in either direction. Maybe *you* aren't doing anything, but background tasks are running, and I would think it would be easy to get the disk into an inconsistent state. Apparently that hasn't happened, but I would think that sooner or later dd'ing mounted drives is going to bite him. Were I going to use this, it would be in single-user mode only. -

Panasonic LF-D201U DVD-RAM   2001 09 
- DVD-RAM is optical storage that: * Is relatively inexpensive * Holds a large amount of data (4.7GB per side at this writing) * Can be re-written hundreds of thousands of times * Has an expected media life of 30 years * Is bootable * Is really ideal for small system backup -

backup mac hfs partition with dd   1997-2004 
- dd works great as a backup/restore tool, providing me with a bootable "mirror" backup of a 1.5-GB OSX operating system in a 12GB OSX partition in 3 minutes time -
using dd for tape backup (network, multiple copies)   1997-2004 
- Used with tar, dd can be quite helpful: This is often when you want to make multiple tapes of the same tar data; do the tar once, dd it as many times as you like. The resultant tapes can be extracted with tar. Another very common use is across networks: tar cvf - . | rcmd otherbox dd of=/dev/tape -

Flyback needs more than ease of use   2007 11 
- Time Machine is not "just" rsnapshot. First, on the tech side, it uses hard links for directories and metadata that identifies a files lineage. It's also much faster than plain old rsnapshot. -
multiple tar volumes to disk   1997-2004 
- You can give multiple -f arguments with some versions of tar. -
Is tar/cpio a good backup program?   1997-2003 
- tar is not; cpio is, to some degree. tar will not back up things like device nodes (and, prior to OpenServer Release 5, it will also not back up empty directories), so a tar backup will not catch anything in /dev, for example, and you will find your device nodes missing when you do your restore. cpio will catch these things. -

Backing up with rsync   2005 12 
- Rsync copies data to another directory, another disk volume, or a another machine. It only copies what needs to be copied. -
Virtual Tape   2005 10 
- Virtual tape does just what you'd think: a backup thinks it's writing to tape, but in reality the data is going elsewhere. It may still end up on tape eventually, but in the meantime it's heading for disk, local or otherwise. -

SCO 5.0.7 DVD-RAM usage   2005 04 
- I'd suggest using Microlite or Lonetar for this. You aren't really verifying with that anyway if you are using stock cpio and the Supertars are far better products - see for example the recent review of Edge at /Reviews/backupedge21.html (similar features are available in the Lonetar product). -

Using rsync for machine replication?   2004 10 
- Yesterday I was at a client site where they explained they wanted to keep a stand-by server up to date and ready to take over in case of main system failure. Fine, lots of people do that, and currently they are doing it by restoring backups every morning. What they were asking about was using rsync or some other mechanism to keep the machines more current. -
CVS   2004 06
