The longer it takes to copy your data, the more data is at risk. A drive may degrade with each attempt to access it. When rescuing data from a dying hard drive, time is of the essence. Linux is an excellent operating system to recover data with a wide variety of open source tools designed to clone and recover data from failing drives. For details of all tools in this series, please check the table in the summary section. Anyone who cares about preserving their data should invest a bit of time in learning about this utility. For this article, we’ll look at ddrescue. The series examines both graphical and text based open source utilities. These are small, indispensable utilities, useful for system administrators as well as regular users of Linux based systems. But, I did have a major success last month.This is the tenth in our series of articles highlighting essential system tools. ![]() I have only had 1 customer in 8 years who agreed to go with the pro's. While my data recovery success rate is not overly high, my customers do not want to spend the $400 minimum for professional data recovery. If I have to clean up space for a current customer, I delete the oldest first and then get rid of the images where there was really not much wrong with the system.Īs for using ddrescue for recovery purposes, I did a lot of reading of posts here on Technibble and then asking lots of questions that I did not find the answers to before trying this for my customers. I try to keep customer data for 30 days after the machine is returned to the customer, but don't always have the space to do so. And I'm running the Synology raid configuration (can't remember what they call it) which gives me 6 TB of storage space. I have a Synology 4-bay enclosure with 4 x 2TB drives in it. For machines that I find (or suspect to be) heavily damaged, then I bring them back to my place to do a full image before working on them. Should make for a faster and safer way of transferring data than by going through a USB connection.Īloha My business is very small (sole proprietor) and most of my work is residential and done at the client's house. I'm going to be using a hotswappable raid bay that we will mount client drives in a cartridge and then slot into the machine. ![]() I am also really interested in the recovery aspect of ddrescue as this would prove useful on those drives that are damaged but not quite at that recovery lab level (or have value that justifies the cost of the recovery effort). So making images would eliminate that (so long as you used a unique naming structure and don't overwrite another client's data). I like the idea of it ALWAYS being A to B so that operator error is reduced. Very easy, but there is always the possibility of error. Right now we clone to a rotating stack of shop drives that we write the latest ticket number and the date on a label. How long would you hold onto the images? The capacity of your cloning station must have been significant, no? Boy so you'd hot swap in a client's drive into the docking station and then clone it to an image on your linux / win box. ![]()
