Resolved Restore from Dropbox

[Pier]

Server operating system version

CentOS Linux 7.9.2009 (Core)

Plesk version and microupdate number

Plesk Obsidian Version 18.0.52, last updated on April 25, 2023 01:17 PM

Hi all,
I manage 5 different servers running Plesk, all but one can't access the dropbox backups for some reason. The dropbox backup have been running fine but since about a week or so it doesn't.
Dropbox backup version is 4.2.3-64

Symptoms:
if I go in the backup manager I get this:
Warning: Could not display the list of backups in the Dropbox Backup storage: Unable to get dumps list: pmm-ras failed (Error code = 1): (1): expected value. Please check the storage settings.

If I try to run a backup manually (on dropbox) I get this:
Error:
Unable to create the remote backup: <unspecified file>(1): expected value

Warning:
Unable to delete the incomplete remote backup. Error: Failed to exec pmm-ras: Exit code: 1: <unspecified file>(1): expected value

If I try to run a backup locally it works
Note: apparently something is saved on dropbox, if I access the dropbox website I can see the files with expected dates and sizes but, since I can't access

What I did:
1. I emptied the directory in dropbox
2. I logged out from dropbox and then logged in again
3. I tried to disable the Validate backups via checksum option
4. I tried to change some parameters in panel.ini , specifically:
[ext-dropbox-backup]
ConnectionTimeout = 60
MaxResumeAttempts = 30
PauseBetweenAttempts = 40

Anyone else?

Hi @Pier, sorry to read that you are experiencing an issue with Dropbox backup. I checked our files whether we've seen the "unspecified file" issue before, but it seems that this is a very specific error that has not yet shown up elsewhere. That only one of your systems is affected also points to some specific problem. Maybe some read-only files in the Dropbox account (that could be a result from inviting other people into the same account)?

In this case I can recommend opening a ticket with Plesk support and let them check the issue directly on your server. If you have bought your license from a reseller, you can still get support. For that case, please use the 30-days trial:

Good morning Peter and thank you for your replay.
Actually I have the problem on 4 servers out of 5 but anyway I will do as you say and I will open a ticket there.
Thanks

Just to add to this but I'm experiencing the same problem. It seemed to start when I upgraded to 18.0.52 just a few days ago. My license is from a reseller so I will have to try the 30-day support trial.

I received this from tech support:

This issue was confirmed by our developers, and it's identified with the ID EXTPLESK-4582. At this moment, there's still no ETA to fix this.

Hi @FutureX, I was just about to post the same ... Yes, unfortunately a product issue. No ETA yet, but extensions are often fixed much faster than core issues. I hope this will be fixed soon.

 

[FutureX]

Yes, hopefully very fast as my clients get a bit unnerved when they continue to see the email with the error.

An update has been published a few minutes ago. It should become installable very soon. Please use the extensions manager to update the extension to the latest version.

Happy to report that update worked! It auto-installed yesterday morning and today had no problems with DropBox backups.

I do confirm: it's fixed!
