[Leica] Software question

[Adam Bridge]

I’m a huge fan of ChronoSync by econ. You can read about it here:

It’s incredibly robust and flexible.

That said I also use Carbon Copy Cloner (CCC to its friends) to make full disk backups of my boot drives and repair partions. It’s good software, well maintained. Because I got ChronoSync first I haven’t explored using CCC to simply move directory portions. I have to feel it would do a good job, however.

One other thing: you want to know if your image files haven’t been corrupted in some way. (It happens, has happened to me when a disk went seriously amuck). So I use a utility from diglloyd called IntegrityChecker that computes a robust checksum for each file in a directory or directory hierarchy. It works just fine but I’m not a fan of the way its sold. Unlike CCC or ChronoSync, which get continuous updates through major versions, diglloyd has a limited window for updates. This stinks. BUT, this is software that shouldn’t have to be messed with very often, even with the upcoming change in the Mac’s file system.

You can find the digilloyd tools at: <https://diglloydtools.com <https://diglloydtools.com/>>

II have a 2013 Mac Pro with a Promise Pegasus2 R6 RAID sitting on a Thunderbolt external link where I keep non-working images. I have a couple of SSDs in and OWC Thunderbay IV external Thunderbolt case along with two other drives. I keep the catalog for Lightroom and my “working” and current (this year’s) images on one of the SSDs (a fast Samsung). For backup purposes I have a drobo connected via FireWire. I use ChronoSync to backup to the drobo on a routine basis. It just moves the files that have changed. AND I use Backblaze to backup to their cloud storage (my off-site backup). It took a LONG time to back everything up and I got stern warnings about bandwidth use from Comcast while I was doing the backups. If something goes amiss and you need to restore from the Cloud Backblaze will send you your data on returnable hard drive(s).

Now that you can buy 8TB of storage for less than $400 it’s silly not to make a full duplicate of your image library even if making it takes a weekend.

ps: I had to correct myself several times writing 8MB instead of 8TB. My first hard drive was 10 MB. The CACHE on most hard drives is at least an order of magnitude larger than that not to mention the caches in the processor itself. The world has seriously exploded since I started with computers in the late 70s.

Any idea if this exists? I have asked an Apple dealer and said me that this doesn’t exist…
