Exclude files in time machine backup mac 10.13.4 how to#The resizing steps seem to be important skipping them resulted in a 10-hour file copy that yielded an 8TB volume containing a 3TB filesystem that I couldn’t figure out how to resize. You can repurpose the old one, or stow it somewhere safe in case something happens to the new drive. Now you can enjoy your new, more spacious Time Machine drive. ![]() Most of that time was spent by macOS fscking. This took ~ 3 hours for me, with about 5 years of backups. Now, expand the volume to take up all remaining space on the drive: sudo diskutil cs resizeVolume $new_lv_guid 0 If you get a permission denied / operation not permitted error here, go into Security & Privacy Preferences and add Full-Disk Access for Terminal.app.įor me this took about 10 hours-I let it run overnight-but, with pv, at least you get a progress meter with an ETA. Exclude files in time machine backup mac 10.13.4 full#It’s very easy to accidentally overwrite your full backup drive with the new blank one here. You need to get the disk numbers from the diskutil cs list output. This is a lot like using dd, except you get a progress meter with ETA. Using the pv command from homebrew, do a low-level block copy of the disks. In my case with a 3TB drive it was 2,999,772,905,472 bytes: sudo diskutil cs resizeVolume $new_lv_guid 2999772905472 Use the exact byte size from step2 as the size of the new volume. Use diskutil cs list in the terminal to get the exact byte size of the Logical Volume on the old drive, and the GUID of the new Logical Volume, as well as the disk numbers for both, e.g., disk4.Erase the new disk with Disk Utility, matching the format of the source drive: MacOS Extended (Journaled, Encrypted).Trying to do a restore in Disk Utility errored out with “unable to validate source” or “Operation not permitted.” Trying some other suggestions in this post and others, I was able to get exciting new error messages like “Catalog file on image/volume is too badly fragmented,” but no copy. Migrating a full 3TB Time Machine encrypted drive to a new 8TB one on macOS 10.14, I ran into all sorts of issues. With "Erase Destination" UNchecked : The restore never starts and I get:Ĭould not restore - Operation not permitted.Back up as many of your files as possible, reformat the disk, and restore your backed-up files.ĭon't know if I'm even suppose to verify/repair a TM disk. Updating boot support partitions for the volume as required.Įrror: Disk Utility can’t repair this disk. I then tried to verify/repair the disk and got: But in Disk Utility, it shows a 1 TB partition! My destination disk is actually 1 TB but after the restore, it shows as 200 GB when I get info from the finder. The weird thing is that my destination disk is EXACTLY like my source disk.even the size. However, my destination disk does get a copy of my TM files. With "Erase Destination" checked : Each time (I've tried twice), when the restore has finished I see a message "Could not restore - Invalid Operation" and "Could not restore - Invalid Argument". ![]() I've tried some of the methods that people have suggested below, specifically using Disk Utility's restore function and it's giving me some error messages and unexpected results (at least to me). I probably can tar up the entire folder and then do a copy, but will that interfere with any of the file permissions, etc.? The one thing with this approach is that I don't have any more space on my source volume for the tar. Is there a faster way to copy these files via a terminal command so that it doesn't perform all of that file counting prep? I got and error that "The operation can’t be completed because backup items can’t be modified." So my plan is to delete the incomplete copy on the new drive and then try to copy over the Backups.backupdb folder again. I then tried to copy over the ones that didn't get copied.but the OS wouldn't allow me to do that. In the morning I saw that only certain backups(folders with dates) got copied over. ![]() I initiated a file copy overnight (b/c I saw that it took OSX forever to prepare for the basically was counting the files for hours). I'm trying to move my time machine backup files all under Backups.backupdb to another drive. ![]()
