<div dir="ltr">The narrative I'd seen was that SSDs are like light
bulbs -- they work and then they don't, and they don't last as
long as HDs, but this was all hearsay, which Gary reasonably
questions. In my case, I'm using a 128GB SanDisk that I got from
Newegg awhile ago with the intent of using it when I finally got
off of MythBuntu 10.04/Myth 0.23. Because of the sudden failure
storyline, I thought a mirror would be prudent, but I had hoped
that the HD wouldn't bog down the I/O performance -- it would
just take awhile to catch up with any backlog.<br>
<br>
The comments made so far have made me rethink that approach. Now
I'm kinda liking the idea of a daily anacron job to rsync the
system to an HD, or maybe better to "tar czf" and logrotate
several day's worth so I can backtrack until I get a working
instance in case a problem isn't immediately apparent. It'll
take me a day or so to mull over all that should be done, cobble
up a script that looks solid, and give it a try when the next
multi-hour window of system inactivity opens (since I'd have no
idea how much time it would take until I try it). If trials look
practical, then I can add it to my daily housekeeping process
that runs once per day on shutdown. If it takes awhile to run,
I can adjust the minimum-time-before-next-recording requirement
to prevent shutdowns that would not provide enough time to get
the work done before the next recording was supposed to start.
If that time window is too large, then I'll just have to think
up another solution.<br>
<br>
Despite what one former supervisor asserted, there really is
more than one way to get something done and the most obvious
isn't necessarily the best, so I try to be open to other ideas.
In that vein, please feel free to poke holes in my revised plan
of attack. ;-)<br>

I would skip the mirroring approach and just make a regular backup.
I use rdiff-backup and keep about one year's worth of backups. I
have a backup script that removes increments older than one year and
then backs up the current system. I used this on all of my linux
systems. I backup to a different machine. I use rsync to mirror my
myth video and myth music libraries. This has come in handy a
couple of times when migrating my myth video library to a larger
drive.<br>
<br>
I too have tried an SSD twice, and each time it died hard. Each
lasted about 1 year or less. I will not purchase another SSD. My
experience is that good old rotating HDs are more reliable.
Coincidentally, both SSDs died the same way doing the same thing (a
mythbuntu update).<br>
