TimeMachine hangs in Waiting to Complete First backup error, when prompted to backup now, it hangs with error Backup Disk not available

Dear All,

Since 2022 I had no issue with TimeMachine. This year after October 31st (with a couple of update on the OS, now I am at 12.7.1 with MBP Retina 13inch early 2015) TimeMachine does not create any backups. It hangs with the error message in the title forever. Safeboot, other forum ideas won't move me forward. I restarted QNAP NAS, MBP, everything several times, i did overnight long run to do backup (sometimes in the past let it sit on power for the entire night helped and resolved, now nothing. I started to check the logs and here is what I see so far... I believe there is an issue that Timemachine somehow looks for Backups of bob007-laptop 19 folder under Volumes, but there is nothing there...

Here is how my Volumes folder looks like:

Log will be on the next post as I get an error message during writing this post.

If i read this right when TM would like to mount '/Volumes/Backups of bob007-laptop 19 as disk3s1 then it fails because there is no such directory. OK it is true... i have no idea why that happened. Between 31.10.2023 and today there were a couple of OSX updates as well, but since I am in 12.x.x that did not caused anything bad in the past.

Does anybody has any idea how to force TM to either pass directory 19 and move forward or redo directory 19 or anything really... I am completely stuck here. I also tried in Terminal with tmutil app, but did not succeed.

Thank you!

How do I run a check disk on QNAP NAS?

QTS will scan the specified volume, even if QTS has not detected any errors on the volume's file system.

Go to Storage & Snapshots > Storage > Storage/Snapshots.
Select a volume.
Click Manage. The Volume Management window opens.
Click Actions, and then select Check File System. ...
Click OK.

I ran a full check file system on the QNAP NAS on top.

Now i tried to backup with TM i got a new message. All backups are corrupted or not readable or I I do not know now :( but I got 2 choices... select a new disk or erase everything and start over. I choose erase everything. Now something is happening as shown here:

I just do not know that my old backups are gone with this way and we start from new or TM will be able to save that. I am 99% sure that my old backups are gone :(

It is not a tragedy at the end, but I found really frustrating that in every 2-3 years somethings goes bad and the only solution is to start from new.

Luckily I am not so desperately need and rely on backups :)

I will wait until this 3h backup finishes and let you know if it works or not.

Thanks for the tip !

I was able to run the First Aid on the Macintosh HD which is my laptop main SSD. No errors were found, after that still waiting for first backup to be complete.

I am not able to run it on the QNAP NAS TMBackup section as Disk Utility does not see it.

Do you have any suggestion how can I make sure that Disk Utility sees my QNAP NAS TMBackup drive?

In Finder I can connect to QNAP NAS with my TimeMachine account and it works. AFP and also SMB

Ohhh that one, yes I ran that, it went through without any issue, any findings. TM still won't preform backups. Now I am trying to leave the laptop open for more than 48h, connected to power source, next to the right Router (no extenders, etc), but I am not sure if this will resolves itself automatically.

Do you know what else can I check or preform on my end, which might help you further?

I tried that, but did not helped either.

The logs are in this thread, somehow TM lost the directory 19 and hanged up there.

Now TM deleted all backups (i personally find funny that it cannot delete just 2 or the last one which probably corrupted) and we start from zero.

TM now works. As said I am used to this, kind of every 2-3 years I need to wipe out all backups because TM stucks with some stupid error, which then no "simple" solution.

Now I will keep this thread in my favourite and if next time something similar happens I can compare the logs at least :)

Thanks for your help! I mark the QNAP answer as solution, but honestly after that fully system check, TM returned with a new error, where I had no choice (as I have no other backup disk :D ) to erase everything and start over :)
