Disable timemachineeditor high sierra7/14/2023 For example, if you rotate between a pair of external hard drives, CCC will not backup to both of them even though they have the same name (e.g. While beneficial, this behavior can sometimes have the wrong result. By verifying both of these identifiers, there is less risk in, for example, backing up to a volume that has the same name as your usual destination but is not actually the destination. As I said, I use TME, have done so for a long time and it works well for me.īy default, CCC uses the name and Universally Unique Identifier (UUID) of your source and destination to positively identify those volumes. TMS and TME both run in the background, wake up TM at the right time, run it, then turn it off again, all automatically. I'm thinking of going to just midnight, but just haven't gotten to that yet. I don't need that, so I set mine to noon and midnight. ![]() If your data is critical and time sensitive, you may need to backup every hour or more frequently. An unfinished backup is not much good if the drive fails. If you need the data, keep the backup drive attached. ![]() If the backup drive is not there, TM will just do what it does, make a snapshot.ĮDITORIAL: Snapshots are, to me, pretty useless. At the interval you set, they start TM, do a backup and then turn TM off again. They way they work is that you leave TM OFF, but the drive attached. What TimeMachineScheduler and TimeMachineEditor do is allow you to set a longer interval between backups. It depends on that database integrity for that to happen. On a restore, you pick the time you want to restore to, TM then checks that the file(s) you want restored are either actual files or links, follows any links back to the unchanged version of the file and restores it for you. If there are snapshots, it puts them into the backup, then erases them from your internal drive. ![]() When you connect the right drive, it finds the folders it's looking for and proceeds. When you attach the new drive with the same name, TM looks for its files, doesn't find them and errors out. When the backup drive is absent at the time of a backup, TM takes a "snapshot" of the drive and stores it on the drive itself as a holder, waiting for the backup drive to be reattached. When TM runs out of drive space, it will delete the oldest backups first, either notifying you or not, depending on your settings. TM files should ONLY be touched by TM itself because when it manipulates the files, it fixes the links as well. If you reach in with Finder to do something, you can break the linkage and destroy the integrity of the backups. That link may go back 1 or 2 or 3 or 50, or more, backups (maybe even all the way to the base backup if the file never changes). When you look at the backups in TM, it looks like all the files are there in each backup, but all that is there is a special kind of link to the last time the file changed. After that, it only backs up things that changed since the last backup, called an incremental backup. At the first backup TM backs up everything. It also deletes old backups automatically for you, you should not touch them with Finder or any other tool. TM backs up every hour by default, can't be lengthened, but can be shortened. The short answers are that it would be best to rename the new drive to something different to keep from confusing TM. Turn off bluetooth and wireless while running Ableton (I don't do this but that might help if you have some online stuff running in the background).OK, thanks for the information. Lastly, use TimeMachineEditor app to prevent your system from backing up your laptop during for instance day times (in fact whenever you're using your MBP), so that when you use Ableton for example it doesn't start and use CPU. Remove as many running apps in the background as possible (I only leave Dropbox). ![]() Use AppCleaner to uninstall useless apps cleanly as well. Use OmniDiskSweeper to identify useless, large files that you can get rid of (be careful though, only non-system ones). Feels like a brand new machine! Do this maybe every month.Īnd keep as much space as you can on your SSD drive (I have like 150-200GB free out of 500) while keeping everything else on a large external drive (SSD if possible as well). This is a game changer, I only found out about it last month. In terms of Mojave performance execute this in Terminal to reset launch services: sudo /system/library/frameworks/amework/frameworks/amework/support/lsregister -kill -seed -lint -r -f -v -dump -domain local -domain system -domain user -domain network Without risking not being able to downgrade back to Catalina as well. I will probably need in the near future a new 16 inch 2020/2021 MPB running on the side to make sure starting from a fresh Time Machine backup with Catalina wouldn't fuck everything up. I refuse to upgrade from Mojave to Catalina with my 2019 MBP as long as I have no guarantee my 350+ k'd plugins & librairies won't be affected by this move.
