"ARQ backs up whatever paths you tell it to back up. Yes?īut I believe that is not the case as I asked ARQ support this question and his answer was: When the Mac2 is powered up, ARQ should not run as ARQ's scheduler is looking for the source named HD1, but can not find it. I have an spare drive named HD2 and I make a clone of HD1. This Mac1's main drive is called Macintosh HD1. I have a Mac1 and ARQ is doing hourly backup. From ur answer, ARQ identifies drives by their names. I am very confused about how ARQ identifies an internal or external drive. ![]() Only if not too much trouble, screen shots will help me more. Then test the SSD to see if full restore does work. Able to disable ARQ's upload and put ARQ on manual will allow me to do a full restore from ARQ backup in the cloud to the SSD. (1) before turning on the test Mac with the SSD (with ARQ running) as an external drive, shut off the house wifi (2) turn on the Mac and hit ARQ's "stop", if it attempts to upload (3) go to ARQ preference and select "manual" (4) turn on house wifi.Īlso I have been using ARQ to backup the entired Mac instead of the home folder and for a long time I have not been able to test if the backup actually works. As a result, I have not been able to test if the SSD is working as an externally boot drive unless I can stop ARQ from uploading to the cloud.ĪRQ support agreed that these steps will stop ARQ from uploading during the test: I was so scared that I shut down the SSD immediately because it might ruin the ARQ backup in the cloud. The first time when I used the SSD (with ARQ's scheduler running) to boot another Mac, ARQ in the SSD started to backup to the cloud (without asking for another password as mentioned by BigMcGuire). This SSD can be used to externally boot another Mac in case I lose my main Mac. In addition to ARQ and time machine, I also do a daily backup of my entired Mac (which has ARQ working) using carbon copy cloner on a 1TB Samsung T5 SSD. The reason I asked these question was I wish to test an SSD (with ARQ running) as an externally boot drive. Acronis got users complain about their download speed and I found no detail about their encryption method.BigMcGuire, Thanks for ur time to answer my ignorant questions and I appreciate it. And backblaze requires sending your encryption key to their server for restoring, which makes no sense to me. As for the rest, I didn't have a good time with duplicati two years ago. If I give up arq completely in the future, I'll use Duplicacy as a replacement.Ībove are what I spent time on for the last few days. But overall it works smoothly which is most important. The web-ui is a little bit glitchy, and I personally feel the settings are somehow weird. I think its idea utilising file path as a substitute to database makes the software relatively simple thus more reliable. Like tarsnap, the sorce code is available but the license is not free.ĭuplicacy starts form 2016 (according to github), records are not long but good. It supports all major platform, can send backups to S3/GDrive/ODrive/Dropbox. I basically just pay for tarsnap to say thanks to the author :) And the price is expensive (0.25$ /GB/Mon for storage, 0.25$ /GB for traffic). Tarsnap can only backup to storage provided by author (essentially S3 from amazon). I learned a lot about general backup tech by just reading the manual of tarsnap. The author really knows every detail about this backup thing and explains very well in the document. The author, the software, the documents and its business model all together is a big HARDCORE. The source code is openly available, but the license is not open-source. This comes from FreeBSD security officer Dr. ![]() Borgbase is new and designed for borg, it's easier to use with borg than rsync. rsync seems professional and doing very well to provide simple reliable storage, also have a long good track. There are some ready to use providers besides building yourself a VPS. One downside for Borg is that it requires server-side support, so you can't put your backups to S3, Dropbox or Onedrive. (This kind of check is weaker than a completely integrity verification, for the detail please read ) People are satisfied with its reliability.Īnother thing I like about Borg is, it can check CRC32 of the segment on server side and even try to repair it! This means you don't need to download everything to client, therefore very fast. ![]() And according to what I got on Google, its 10-years-long track seems pretty good. The software is open-source and well-documented. The core is written in C/Cython thus highly efficient. It works on Mac and Linux/Unix, with carefully designed encryption and deduplication. Having study this for days, and omg backup is no easy job even you're willing to pay for it.
