Be careful with sudo and making sure you pick the correct Mac's files since there is no undo or confirmation of the following command: sudo tmutil delete /Volumes/drive_name/Backups.backupdb/old_mac_name The sudo command needs your password (and it won't echo to the screen, so just type it and pause to be sure you're dating the correct files before ...

The easiest way is to: Enter time machine (on the Mac whose backup you want to delete) Go to the point in time you want to delete Select the icon that looks like a cog in the finder and choose 'Delete Backup' (in Mavericks: Right click in the finder window and choose 'Delete Backup') This ensures the backup catalog remains accurate and the integrity of ...

For Mavericks/Yosemite Enter time machine Select the backup Right click on the backup (on the finder window) Select 'Delete Backup' It will ask the password and you are done

The command tmutil compare lets you compare file lists if you don't want to do it using ls or other commands that can show differences in files and folders like rsync and many graphical diff programs. You can list backup paths and then copy them into the compare command. Example: sudo tmutil listbackups sudo tmutil compare "path1" "path2" Many people ...

If you're interested in seeing what files are being read as the backup happens, you can use this command: sudo opensnoop -n backupd | grep -v 'Time Machine Backups' Note: the above worked in earlier versions of macOS. In High Sierra, something approximating this is: sudo fs_usage -f filesys backupd However there's a lot of noise from the backup volume ...

This script will automatically find the oldest TM backup for your computer, tell you which is the oldest and newest backup and provide you with a prompt to delete the oldest backup. You must enter Y and enter your administrator password to delete it. bash script: COMPUTER_NAME=$(scutil --get ComputerName) NBACKUPS=$(tmutil listbackups | grep "$...

I'm pretty sure you can't, and you wouldn't want to. The OS only bypasses the bundle for locally attached backup destinations. Direct attached storage (DAS) uses the HFS+ filesystem and /Backups.backupsdb folder structure Network attached storage (NAS) uses the sparse bundle format to embed a HFS+ filesystem on whatever filesystem that the NAS uses natively....

I've been asking myself this very question, and the answers on here certainly helped. However there's an aspect that's lacking which may be a new implementation "detail" that didn't exist when this question was answered. tmutil delete does indeed delete backups, but doesn't actually reclaim the space they took, at least not in any guaranteed way. I spent ...

If Time Machine is really only backing up differences, deleting in reverse order is not what you want. Plus given that each delete can take some time, having a script that will delete the next one when the current one completes would be nice. Following user36971's sample script above, I've written up one that'll delete all backups from the one specified and ...

Yes, this is possible and actually quite simple. To prevent the Time Capsule from acting as a WiFi access point or router, and use it only as a backup disk, just open the AirPort Utility app on a Mac (Applications -> Utilities -> AirPort Utility) and do the following: Select your Time Capsule and hit Edit. Go to the tab labeled Wireless (not Network as ...

According to Apple (from the Time Capsule manual) Using Your AirPort Time Capsule Safely The only way to shut off power completely to your AirPort Time Capsule is to disconnect it from the power source. If you want to go above and beyond, you can be sure that all users all logged off, and not performing a backup through the Airport Utility, but this is ...

Yes, using the Airport Utility you can turn off the router and WiFi functionality independently of each other. Under the Wireless tab - Network Mode: select Off Under the Network tab - Router Mode: select Off At this point you can connect the Time Capsule to the wired network using the ports with a horizontal icon <-> or even use it to receive the ...

If you are trying to extend a wireless network that is not an Apple Airport base station it cannot be done. You can join a network but this will not increase the range of your wireless network. Unless you have a firmware that supports WDS on your 3rd party wireless router.

You can use timedog for that. timedog is a Perl script that displays the set of files that were saved for any given backup created by Mac OS X Time Machine. By default it shows those files that were saved in the most recent backup. The listing includes the file sizes before and after, as well as a total file count and size. The script includes an option ...

To adjust the schedule in order to backup at a time more to your choosing than simply every hour, you can use the Time Machine Editor tool, which is available as a free download from: http://timesoftware.free.fr/timemachineeditor/ TimeMachineEditor is a software for Mac OS X Leopard, Snow Leopard and Lion that lets you change the default one-hour ...

Yes. Each Mac get's it's own sparse bundle disk image.


8

Yes, it's straightforward to do it, even though it would take quite sometime to complete depending on the size of your current backups. Follow the detailed procedure at Copy Local backups to be used on a NETWORK. Here's a summary of what's required and the steps. The backups go into a sparsebundle on a Time Capsule. So you need to create that ...

Alright, I see you've added some requisites to your answer. Here goes. Part 1: Install Ubuntu 16.04 Server. Download this. (Ubuntu Server 16.04 32-bit) This is done the same way any other Linux install is done. You will insert the CD/DVD, run through the setup to take the entire partition of the Mac Mini, and once you reach a desktop, you're ready for ...

She could probably tie the time capsule into a ethernet line in her dorm (I assume there is a wired option) and then set the time capsule to be on bridge mode (where it doesn't issue a new IP adress but rather passes the one issued by the school's DHCP). She could then use her Time Capsule (which is also a wifi router) to have her own private wifi locked ...

According to Apple, Airport Extreme with attached disk is not supported for Time Machine. It might work, sometimes, but with a backup system, people usually want more than "might work sometimes".

If you want to watch which files are being transfered in realtime you can monitor the time machine daemon with sudo fs_usage -f -R filesys backupd If you see abnoramly large file transfer you might see disk images from virtual machines in the list


7

Yes. Time Capsules can be used for Time Machine backups as well as for general storage, though Apple recommends against it: Time Machine works best if you use your backup disk only for Time Machine backups. If you keep files on your backup disk, Time Machine won’t back up those files, and the space available for Time Machine backups is reduced. I ...

First of all, I would suggest setting this up with the Time Capsule first (unplug the AirPort Express). Then, once you have it working on the Time Capsule, you can duplicate it with the AirPort Express. Option 1 If you want to lock things down as much as possible, then "No Access" should be the default: And then create a new entry for the cell phone for ...


7

The only feature that needs to be enabled on the Time Capsule is the file sharing feature. This will activate AFP and SMB Filesharing which allows your Mac, PC and Android Device to access the Time Capsule and use it as a NAS (basically the Time Capsule is a glorified NAS). To access your file on the Time Capsule you need a SMB client for Android such as ...

The AirPort Time Capsule (the official name, with my emphasis added on AirPort - see below for the reason), runs NetBSD, according to the Examples of use section for NetBSD on Wikipedia. It cites two sources - one being an answer from superuser.com (not very useful in this case), and another an article on wifinetnews.com, that states: A source unconnected ...

According to Apple, at https://support.apple.com/kb/PH21902?locale=en_US If you add a Time Machine backup disk to the privacy list, you will continue to see messages that Spotlight is indexing your backup disk. This indexing is necessary for Time Machine to function properly and can’t be disabled. Spotlight does exclude from searches any items you ...

The canonical way to check status of time machine is to use the utility and check status: tmutil status Now, you have to process the text since it reports exit 0 when running and when it's not running since the status returned - not that there's a correct status. I would use: tmutil status | grep "Running = 0;" That returns 0 if the system is not ...


6

I'd suggest using rsync from the terminal. It may still be slow, however: It should be faster than finder. You can stop the transfer any time. It will resume from where you left the next time you issue the same command. So, it should both reduce required time and also make it possible to stop it and resume if you actually need to use your computer. sudo ...

The Time Capsule can only "extend" a wireless signal....using wireless only....from another AirPort Extreme, Time Capsule, or AirPort Express. Apple is doing this in a proprietary way and non Apple hardware is not supported. In any case WiFi extension is generally flaky and to be avoided. I strongly recommend you look into using Powerline plugs like these ...
