Chat about Snapshot

[Jakob77]

If your USB-stick is all too big for your snapshot iso don't start crying about the waste of space.
In advanced options you can just make a partition for data and use that as normal without booting on it.

That is a good thing because the installation USB with MX Wildflower and Snapshot has an exiting tendency to breed.
And along with a list of setup things to remember my USB library is growing.

Some users in other distros can do a backup.

In MX we can make history.

I have installed MX on two computers with Snapshot from USB-sick today.

That gave me the output

Code: Select all

QProcess::UnknownError

295 times.


Who knows what the unknown can be.?
And how can the install still seem to work okay with so many errors.?
Some files on the desktop got their permissions changed but so far that is the only unexpected thing I have seen.


However I think it might be a good rule not just to rely on a snapshot iso file.
In my system I have decided a Snapshot backup is not really done before I have a test passed USB-stick in my hand.



And a question I have had some fun thinking about and want to share:
To do a md5 checksum test on the iso file right after it is made.
Is that silly or not.?

I believe that is a QT error, but without a real code... ??

I think it wouldnt hurt to know that the iso is good. As I said before, I have not had issues with writing iso's.

In walking through the steps, I use etcher to write ISO's .. never thought about that before, but that is a difference.

What exactly gave you the error? The installer? Anything else that can give us an idea? We are lacking context to understand what is going on. If for example you see in a log QProcess::UnknownError it might be useful to know what command was tried to be executed which might be listed before the error...

[AK-47]

QProcess::UnknownError doesn't mean anything per se, and it depends on other parameters. The installer logs other codes also, for instance, if it looks like this then it is likely that the process executed successfully:

Code: Select all

Exit #8: 0 QProcess::NormalExit QProcess::UnknownError

That "#8" can be any number, and has nothing to do with the error. The first field after "Exit #...:" is the return code (should be 0 in most cases), the exit status (should be QProcess::Normal Exit) and the error code (defaults to QProcess::UnknownError).

[Jakob77]

Thank you for asking. Yes that is mainly what it is:

Code: Select all

Exit #1: 0 QProcess::NormalExit QProcess::UnknownError

Exit #157: 0 QProcess::NormalExit QProcess::UnknownError

Maybe it can occur if the USB is hardly big enough but the target computers still don't seem to mind.

Yes, and very good to know it is tested that the snapshot iso file is also compatible with Etcher.
So if we want to restore an iso file 10 years later we are not necessarily depending on snapshots USB Maker to be that much backward compatible.
I just think the Snapshot USB Maker is so nice and straight forward when I for instance also want to add a data partition.

I have no idea what your asking / saying here about backward compatible.

And just to clarify, there are two different tools we are talking about here :
1) MX Snapshot ( Creates an iso of your computer )
2) MX Live USB Maker ( Writes an ISO to USB)

And if your asking about a writable partition ( ie .. persistence ) , then yes the MX Live USB Maker is the way to go.

I have seen so many "smart" backup systems that works really well for people until the day they need a restore.
Windows backup systems, DOS programs, Windows programs, Outlook and Thunderbird mail databases, forum databases and so on.
Therefore I like that it has been confirmed the snapshot iso file is a normal iso being compatible with more than just one peace of software.

[CharlesV]

And this is *exactly* why you should ***test*** your backups routinely!

A backup is ONLY as good as the ability to restore it! I learned long ago that if you want to be sure, you must test backups, and so every three months I test my backups. Timeshift, Snapshot and BackInTime - all are tested!
