Flash backup stays as "unconfirmed .crdownload". Does not create zip

[xrqp]

I am trying to upgrade my unraid flash hardware to a faster one. I am using Win10 PC, and unraid web interface, and go to Main, then Flash, then click "Flash Backup" button.  It goes to my Win10 downloads folder, but it stops and ends with the file name "Unconfirmed 551776.crdownload".  I rebooted unraid and tried again w same result.   Then rebooted Wind10 and same result.

 

I recently updated to Unraid 6.9.2, but before I updated from 6.9.1 I was able to create flash backup.  It created as file name "tower-flash-backup-20210824-1742.zip".  What should i do - go back to my last backup of 6.9.1 ?

How much RAM do you have on your server? How large is the flash drive?

on the unraid tower, the flash is 16GB.  and Ram is also 16GB.

Why bother to upgrade your flash - it will not make UnRaid run any faster as after initial load UnRaid runs from RAM.   Practical experience has also shown that USB3 drives are far more prone to failure than USB2 ones.

Absolutely no good reason to do this. Flash speed is unimportant. In fact, booting from USB2 port is more reliable.

 

Flash is used at boot time to load the OS into RAM, and the OS runs in RAM. Think of it as firmware except easier to work with. Any settings you make in the webUI are stored on flash so they can be loaded at boot also. Other than that, flash doesn't get used much. Speed and size are unimportant.

I want to boot faster.  Seems like I need to boot or re-boot often. Does not faster flash speed make faster boots?

"USB3 drives are far more prone to failure than USB2 ones"  Is it still that bad after all these years? 

I was going by SpaceInvaderOne video about the flash he tested.  He only used a standard flash test app, not unraid test.  He made a guess that the pro-USB2 (anti-USB3) for unraid may have been long ago, and may be is no longer true.

 

Don't forget my other issue: I cannot do a flash backup since I went from .1 to .2

I went ahead, and put the 6.9.1 backup on my new "fast" flash, 32GB Samsung Fit Plus.  My system does not seem any faster, for shutdown or reboot of unraid.  Roughly the same.  My prior one was Sandisk 16GB UltrFit.  It was USB3 also.
