deleting snapshots after exporting and bugs after #15 upgrade

[Ogy]

Hi, really great work, thanks for it. Please consider deleting old snapshots after successful export of all images, not between exporting. And there is a bug: second disk isn't unprotected before deleting. another a little bug with: "rbd: failed to create snapshot: (17) File exists" (please see log)) another bug: loop will destroy barc snapshot of first disk, cause IMHO keep=2 and VM has 2 disks/snapshots or etc.

because i ran barc at screen, i lost output from it. i've deleted all snapshots and re-ran it again, all errors have appeared again, please see log below

i tried it even without symbol '=' .. same results

eve4pve-barc backup --vmid=135 --label='daily' --path=/snapshoty-sshfs --keep=2

omg, sorry for bold and bad proportions

[franklupo]

Delete all snapshots and (or move) files in directory. Because 2 times "Creating snapshot rbd / vm-135-disk-1 @ barcdaily170925171113"?

[franklupo]

run with parameter --debug and send me output.

Thanks

[Ogy]

thanks, i've done it meanwhile without debug, so i reran it with debug. both outputs included in attachement thanks tomas barc-output.txt

[franklupo]

Can you send me config file of vm?

thanks

[Ogy]

Good morning, sure i can :) in a attachement btw i deleted snapshot testcopy from shell 135.txt

[franklupo]

Execute in host shell

Ok the problem is the snapshot in configuration file VM/CT. I fix problem, reading last configuration.

If you remove the snapshot testcopy work.

[Ogy]

wow, you are right, so i can't have own snapshots ? - i can handle it

[franklupo]

I fix problem in Next release.

[franklupo]

Why

Please consider deleting old snapshots after successful export of all images, not between exporting.

?

[Ogy]

it is safer approach, IMHO things like testcopy snapshot occurs, i've ended with no snapshot on 1st disk.. or any other failure can occur, like disk or network die during exporting. it was just idea.. and i've got a new one :-D going create #17 thanks for your time and efford

[franklupo]

in case of error you would have many snapshots on the image. There should only be a snapshot. The performers would be affected

[Ogy]

thanks !
