Time machine backup not running

El Capitan 10.11.2 resolved the issues of Time Machine backup with an UPS connected and the annoying alarm window doesn't appears more at login startup page.

The startup, it is more slow and if I detach the Time Machine disk the startup is very more fast.

So! I observe that the Startup Bar hangs SOME seconds at 3/4 of System charge. The System, perhaps, before have to identify and to connect the Time Machine disk and, in fact, after the LED of Time Machine disk flashes, the startup bar continues and the login page appears.

I'm sorry but I don't speak English well.

Who of you is British or American and agree with me, can send it a good feedback to Apple?

I hope that Apple can accelerate this process...

Not seeing this at all on my iMac. I have a Fusion drive and the machine boots and is ready for login in less than 20 seconds.

I stopped contributing after getting yelled at for mentioning the betas - but yes, it's working fine here too.

All good here too. This has been an interesting one. I guess now I'm on to my remaining more obscure and less repeatable bugs in El Capitan 🙂

Dear Ikrupp, I have an iMac 27 inch, mid 2014 full optional: CPU i7, GPU 4GB and... Fusion Drive... 😉

My iMac boot in 18 seconds without Time Machine disc (disconnected from Thunderbolt port with FireWire 800 adapter)

But if Time Machine is connected the Startup is of 32 seconds.

So! Thank to you... during this test I have notate that if I have disconnected Time Machine but the UPS-Backup is connected at USB port... the annoying window appears always at login startup.

This window persists only some instants!!!! You can see it if you have activate the login password and if you record a movie with an iPhone, iPad or a Camera...

El Capitan 10.11.2 is bad! The Apple Engineers are not specialist, as the old times...

I am not sure but I believe what you are seeing is normal & not related specifically to Time Machine backup drives. Part of the startup process is to look for every identifiable volume on every connected drive. Since this involves checking each drive's partition scheme, if it is a conventional mechanical drive it must spin up & initialize before this can occur, which can add significantly to the startup time, depending on the drive's characteristics.

You should see similar behavior for any external drive, with its activity light briefly flashing when it is accessed, whether or not it has a Time Machine backup volume on it.

Yes, 10.11.2 fixes the UPS USB issue. I'm also staring at corrupted TM backups. I like to prune my TM backups every so often. For example, deleting all backups of the /Applications directory and other large directories for which I only care about the most current set of data.

After updating to 10.11.2, I went through one of those exercises. Now, my backups for my Macbook (backed up to my iMac via OS X Server) are corrupted. Paging back in time reveals some blank dates (and this isn't a display refresh issue). I even had some things appear I deleted long ago. I'm going to have to wipe all those backups and do a new full backup. I won't trust that, for sure.

After doing the same on my iMac, the next backup should have backed-up the /Applications directory (15-20GB, I guess). Not this time. Treats it as if it has been backed-up already. I rebooted and started a new backup. Been sitting at 'Preparing...' for about two hours now. Not sure what the deal is with this. It's happened before and the solution was just leave it, it would finish eventually, and then everything worked fine after that.

I'm basically at the end of my rope with Apple. Software QA appears to be non-existent. Each new release breaks more things that used to work.

How exactly are you doing this pruning?

If you delete anything on the TM backup using Finder, you are inviting corruption because that does not update the database on the TM volume that keeps track of which unique version of your files appear "in" each of the time-stamped backup sets. (As you may know, TM uses directory hard links to make it appear as if there are copies of the same files in multiple backups, but there really is only one copy of each unique version on the drive.)

Because of this, you should never delete anything from a TM backup from a Finder window, & only use the TM interface to do that.

If you previously used Finder to delete the /Applications folder backup, that is probably why TM thinks it has been backed up. Similarly, that may explain why the preparing stage is taking so long -- TM has to do a "deep scan" of every file & every backup set because the database doesn't match what is actually on the drive.

So has 10.11.2 really cleared this up for everyone? I'm still seeing TM not run scheduled backups 😟

After installing the 10.11.2 update and doing 2 restarts with the UPS/USB cable plugged in, TM has yet to miss a scheduled backup on my late 2013 Mac Pro..

I'm grateful to say that it has for me.

All good now on my 2009 MacPro.

After upgrading to 10.11.2 Time Machine automatic backups worked for a few days, then stopped running.

I tried shut down, power off/on UPS, PRAM reset, reboot, but still no automatic backups.

The automatic backups appeared to stop running after a warning that my Time Machine disk was full. I issued the command

sudo tmutil delete path/to/old/TM/backup

Manual backups complete successfully, but automatic backups have stopped running. I'm not sure if this is causative or coincidental.

I don't see anything in the logs and don't believe this is a specific issue with my TM, so I've issued a bug report.

Hi

Hourly backups are not working for me on 10.11.3?

I have just updated from yosemite to el capitan. When I wake the iMac from sleep it does its first backup fine, but subsequent backups do not start, for example if a backup is scheduled for 17.50 it will skip it and change to next backup 18.50..... and so on.

I though this was fixed?

thanks

Running El Capitan 10.11.3 Upgraded to El Capitan around the new year.

Didn't notice it until now, but TM stopped working on March 3, 2016.

I found a blog that said to run Disk utility. I tried that and once it 'started' the screen never changed. Note: prior to starting, the utility said the disk was full but checking it with GET More said <200G used of 500G. Well the screen never changed so I did a Forced stop/reboot. now it doesn't 'see' the drive at all- sort of. Not on desktop - if I try a manual ** it says no drive. I don't know how but the old space windows with backups appeared once. Just ordered a new WD eHD but it's probably not needed.

Help?
