comment Cost effective, long term archival of video and image data? ~50 TB
Honestly, the difficulty with any kind of CMS system is that it is likely to be the first and most outdated portion of a system. You'd almost be better off requiring everyone to write an ASCII text file with some basic descriptions and store it with your raw data. Any CMS or automated system is going to get old on a scale of a few years.

yeah, we've come a ways. Still, I have no problem playing 17 year old AVI files from windows 3.1 days. The trick lies in choosing formats that are already in wide use.

Lossless video is not currently practical to store. It's simply too expensive to archive gigs per minute of footage. Pick a lossy codec you're happy with now that is in wide use, and leave your media in it.

PDF for images seems like a pretty horrible way to do it. Yes absolutely PDF for documents, but keep the images as tiffs or JPEGS depending on your output format. The capability to read those is unlikely to go away.

+1 for good points on copying, but -1 for asserting that formats will become unreadable. Once the data is available on a copyable medium, those files aren't likely to become unplayable unless they're in a VERY odd format. Archiving to something very mainstream like MPEG2 is extremely likely to be a durable format. Transcoding lossy video is a lossy process. It should not be done. It doesn't cost us much of anything to keep a mainstream video codec around...

comment Should my server have PHP safe mode On?
Are you sure your configuration is correct for Joomla? I believe there are a number of ways that it can be compromised if you don't take great care with the security. Are you certain users can only write to the correct locations on the disk? Do you know that your webserver will not execute code at those locations? Joomla will prevent some of this, but definitely not all of it.

comment ZFS on top of Hardware Mirroring, or just mirror in ZFS?
Mirrored raid generally doesn't have raid hardware compatibility problems, since each drive is a perfect copy. There aren't availability problems for replacing the raid controller, it's an IBM server. That said, I did end up going with pure ZFS.

comment Is private domain registration worth the extra cost?
Also, whatever you do, get a better registrar. Paying any money at all for private registration is too much, and if you insist on doing so, it shouldn't be more than $2 or so. I recommend moniker for small-scale registrations.

@Justin Interesting. I've definitely gotten domain slamming mail while my domains were 6 or 8 months from expiry. I wonder if the prevalence of that sort of thing is geographically biased.

comment raid 5 rebuilding epic fail
For fancier systems like ZFS, you actually do gain a substantial benefit from having bigger arrays rather than multiple smaller ones. Look at the end of this article for the reasoning. dtrace.org/blogs/ahl/2006/06/18/double-parity-raid-z

comment 2 drives failed in raid 5
3TB? You're going for triple redundancy? I would expect that in most cases, that third level might better be served by a separate appliance with lower cost lower performance backup hardware... You must have some serious availability and performance requirements.

comment SSL certificate for a public IP address?
Yes, that would have been a more useful thing to say. SSL certs are needlessly expensive, but on the scale of doing business, the cost is almost nothing.

comment Moving Raid 5 ISA controller card + 4 Drives to another server while keeping data (not boot)
Quicker? I doubt it. As the others have said, the raid controller should retain the information during the move.

comment Encypted backups
Yeah. In order to encrypt your backups, you will need to push the data from your server, rather than pulling it with the NAS. A cron job using DAR to do incrementals would be a pretty good way to set it up.

comment SSL certificate for a public IP address?
How many of your clients are going to do a full background check on your SSL provider? They'd really have to dig before they realized that they were doing business with a company that did business with an Israeli company. As MadHatter said, political instability has very little to do with whether or not your cert is valid. Once it's issued, it's valid until it expires, full stop. But it's cool if you want to pay some other registrar ridiculous money for something that's not technically complicated. SSL certs are one of the most ridiculous scams ever.

The rest of us get a lot of random junk in our physical inbox from scammers trying to get us to pay $100 to renew our domains.
