![]() ![]() Parts of that Synology are uploaded via iDrive (10 TB account) twice a week. All my stuff is duplicated there, some automatically (like DT sync store), others manually using FreeFileSync to sync my carry-on disk, Dropbox files and DT databases, all of that manually sync every 15 days or so. Now with APFS we have started over with fragmentation )įorgot to say I have a second backup strategy, in this case Online: I have a Synology DS1019+ 5-bay disks. (And there is a comic lesson here: fragmentation has been a serious problem in all disk formats, including NTFS, HFS, FATxx, etc… However, across time all implementations solved the issue and latest macOS/Windows/Linux do not fragment (or fragment but in a way that does not affect performance) “classic” disks and formats. If you add AFPS format, then it can become dramatically slow. ![]() You can have a Thunderbolt 1000 tera-giga-gugol speed bus but connected to a 5200 RPM mechanical disk (like most 3.5" portable disks are), you will have the mechanical disk speed, that is, well, slow.If the disk is SSD there is no issue because time to access any cell is the same or almost the same (what slows a SSD disk is not being TRIMmed), but mechanical ones work slower and slower across time. My “carry on” disk has exFat format as I’m a Windows-macOS guy and that is the most reliable format that works in both systems. My pure CCC (or previously Time Machine) backup disks have APFS format to take advantage of snapshots. But don’t worry about these, I could help you later with them. If you want to automate it, and also use Time Machine, etc, that is, going a bit higher-level, than you could use something like a NAS, or OWC Thunderbay with 2 or more drives, etc. Every now and then, plug in the other new drive, and copy using the Finder from yur data disk to this, call it “Backup”. Plug one permanently to your Mac, use it for all your data, that is, videos, Devonthink databases. Get some Samsung or SanDisk SSD, cheap, say 2TB each. So, if it were me, this is what i would do: get TWO new drives, not one. Freeing up space makes it suddenly feel like you just bought it! (if you don’t have other reasons for sluggishness). When the disk starts getting too full, it needs to do a very long and complicated dance to do what it needs to do. Why? because the system uses free space all the tie to move things around. Boot drives (the main one in a computer) DO NOT LIKE to be filled too much, usually it would require at least 20% free. If you filled this drive almost to capacity with other stuff, such as your data files, then it WILL BE VERY SLOW - I am not shouting here, just emphasizing. ![]() Your Macontosh HD - which contains your system and applications, is 250GB. It is COMPLETELY separated from whatever Arq, backblaze, Time Machine would be doing.īY THE WAY Anna, I think I might know a potential reason your computer is slow. CCC is great because it AUTOMATES it.Īnd you would not be zipping anything. But you should not be touching these at all!!!Ī local backup to an external drive, you don’t even need CCC - you can just connect the external and drag your databases to the new drive, period. But it has worked perfectly for me the last 17 years or so.Īnna, how are you getting a zip file from the database?Īrq IS right, there are files left in the computer so that it can sync to the cloud, same will happen with Backblaze. Just for Devonthink, I have about 240 GB of databases, the largest being around 80 gigabytes. If you get CCC, I can help walk you through the process (with the usual caveat that I am not seeing your desktop, so it’s basically advice through here) If you are getting challenged by this and has lots of things, then the more IMPORTANT it is for you to backup up what you have right away.Īs Blanc says, don’t back up to the same drive, it’s slow(er) and quite useless, because if that drive fails, you loose everything. The clone occupies pretty much the same amount of space as the original (minor differences if disk drives, the internal Mac one and the external are very different capacities) Can be your “Documents” folder, for example, if that’s where you store most everything. Then using CCC to create a clone of whatever you want to backup. Local backup means (usually) connecting an external drive to your Mac, which I suppose has USB-3 and Thunderbolt-2 ports (and BTW this is not at all a bad or slow machine). I think you might be misunderstanding what the local backup is. I have several Macs, some are form the early 2000s, and I can do a local backup via CCC (or other apps) in any of them. Anna, I am not sure I understand why it is not possible to do a local backup with a MacBook Pro 2015, even full of junk. ![]()
