Image27.sparsebundle? Image27 is indeed the name of the iMac from which the backup originates?

Absolutely...

I sometimes received this message "no displayable file system", when the system considered that a disk image was corrupted. What needs to be done is to make a new backup with the iMac, then not try to open it locally, but from the Macbook and remotely at first.

Another attempt to be made is to put on this Time Machine disk, from the iMac, a new disk image of type sparsebundle, next to the backup image, created with Disk Utility, just for testing.
So, create this disk image from the iMac, put some innocuous files inside, unmount the disk image, and then try to open it from the Macbook remotely.

Ok, I'm going to reformat the cloud box tonight, make a "small" backup of a folder, and I'll try to open it in remote mode.
For the second attempt, I don't know how to create a sparsebundle image; can I use any downloaded software in .dmg format instead?

To create a disk image, you simply need to use Disk Utility, and from there, request to create a new blank or empty disk image from the menu bar. Then, in the dialog window, you can define the type, size, name, etc. I can't provide the detailed steps right now, as I am currently on Sierra, and the procedure on 10.6 is slightly different.

OK thanks, I'll take a look at that...

I tested it, still the same (I’m talking about creating a hard disk image, etc.)
I placed the new image at the same level as the TM backup, I connected remotely, and still the same error message with either backup:
"no mountable file systems"

So, there must be a corruption of the file image when it passes through the network.

Tests to be done locally and then remotely:

you launch the Terminal, (Applications / Utilities ...)

in the Terminal window, you paste this command

md5

then you enter a space

next, you drag the sparsebundle disk image into the Terminal window, and you confirm.

The Terminal window should display a series of hexadecimal characters, like
5cf0bdeb82c2ae2f87acd4bd88d259d1


do the same thing locally and remotely, you should get the same string of characters if the image is not corrupted via the network...

That's surprising because the disk image, once transferred to the Mac, let's say directly on the desktop, should be accepted by the Terminal.

For example, if I take a disk image located in my Downloads folder:



I will perform the operation with the sparsebundle image I created last night on my Time Capsule...

Indeed, it won't work on a sparsebundle image. This image does indeed contain a directory.

I did another test, I renamed this sparsebundle image to .dmg instead of .sparsebundle... it mounts without any issue, it would be a test to perform from the remote Mac on the test sparsebundle image... (it works on the local network at my place)

I'm trying it out, only MEGA problem, if it works by renaming the .dmg file, I would need to copy a 500GB image of data "remotely" to be able to fit it into the backup! lol
because of course, I can't rename the extension on the mounted backup drive.....
I'm fed up!

No, not by transferring the sparsebundle file, but by renaming the disk image remotely before trying to mount it. Why is this not possible, since you have access to this image?

I have access YES, but I cannot rename the file...

And why? A problem with file permissions?

When you select the file, then request to read its information, you can see at the bottom of the window the read and write permissions.

so...

LOCALLY: I can rename it without any problem (even though it's unnecessary since the .sparsbundle opens correctly)

REMOTELY: I cannot rename it, when I check the properties, in Sharing and Permissions it says "you have custom access"

I also have this line "you have personalized access", but below we see the write and read rights, as there are no restrictions, I can rename the file:

I only have the text line without the permissions or the little table :(

You should then make the modification locally, and possibly check the permissions locally, and even grant yourself read and write permissions locally.

I’d appreciate a little help; I don’t know how to proceed! I’ll give it a try tonight, I’m off :) thanks, Francis

It's easy to change the rights or add a user with write permissions; I wrote a response on this topic a while ago here:

https://forums.commentcamarche.net/forum/affich-10020248-aide-pour-mot-de-passe-svp#1

You can also add a user by clicking the + sign at the bottom of the window, then granting them read and/or write permissions.

Ok thanks. But on which file(s) should I do the operation?

The parent folder is the folder that contains the sparsebundle disk image.

For me, although I am at the root of my Time Capsule, I have this structure,



where we can see that for me, with my test backup made yesterday, the parent folder is "Francis Capsule," which itself is contained in the Airport Time Capsule path of Francis...

Ok, so it must be the root of the cloudbox then. I'm not at home, I'll check later.
Thanks to you.

I tried, I set everything to read/write permissions + admin as well, and nothing works :( desperate.
I'm backing up my cloudbox elsewhere and I'm going to reformat it, last chance...

Hello, so I tried on the root folder called "sauvegardeTM", it says "everyone access denied", when I open the menu I set "read and write", I apply it to the entire folder, I close the window. I reopen it, again "everyone access denied"!
Now when I try on the sparsebundle backup inside the root folder "sauvegardeTM", it already says "everyone read and write"
So that's the update...
I might need to try with the software you mentioned yesterday, I didn't have time ^^
Have a good day

I just tried BATCHMOD, nothing worked either :(
Can you try sending me a screenshot of the correct settings to set in the app, maybe I made a mistake! Thanks.

That's exactly what I did, once applied everything seems fine, a message from the software telling me it's done. I exit, I check the disk permissions, nothing has changed. I repeat the process, I open the software, all the permissions I checked have disappeared and we go back to square one.
I only have the first 3 boxes checked.

and by applying the thing directly on the sparsebundle image?

iGone69 Posted messages 31 Status Membre
 
Yes, I did it, the permissions are still checked there, but I have the same problem as usual in remote mode, as soon as I click on the sparsebundle image: "no mountable file systems."

Well... I can only see one thing, the disk image is not being recognized correctly remotely via the Cloudbox...

and the DiskImageMounter application considers it invalid...,

when DiskImageMounter tries to mount a disk image, it first performs a file integrity check; if this check is not possible, or if the disk image is considered corrupted, it doesn’t mount it... Now, why, when viewed remotely, this disk image is seen as "not mountable"... I don't know... a corruption of the information via the Cloudbox?...

( just for your information, the message is more like "no mountable file system"...)

yes sorry "montable" ;)
as I told you, I will try formatting and starting from scratch... You never know, right!
I'll keep you updated Francis, thanks for everything.
