Failed to process file...FileMissingException: File doesn't exist


#1

Hi guys,

For a couple of day, I get end backup messages saying that it failed to process some files (see below).

Is my backup corrupted? What should I do?

Any help would be appreciated :slight_smile:

Thank you

I looks like the warnings may be coming as part of the post-backup verification step. If so, then the good news is your backups are likely running just fine. :slight_smile:

Some questions I have include:

  • What version of Duplicati are you using and on what OS (Linux, MacOS, Windows…)?
  • Do the warnings happen with every run? (Do they go away if you set --backup-test-samples=0?)
  • When the warnings happen are they always for the same file? (Is it always a dblock.zip.aes file?)

#3

Hi @JonMikelV,

What version of Duplicati are you using and on what OS (Linux, MacOS, Windows…)?

Duplicati - 2.0.3.3_beta_2018-04-02

Do the warnings happen with every run? (Do they go away if you set --backup-test-samples=0?)

No, I noticed these warnings a couple of days at the first run on the morning only and I didn’t see any new one till I post in this forum!?

When the warnings happen are they always for the same file? (Is it always a dblock.zip.aes file?)

I don’t remember but I think so…

What is the next step?

Thank you for your support


#4

I forgot to ask what destination you are using, but it sounds like the issue is most likely that after completing a backup Duplicati is trying to test the files that were just uploaded and the destination isn’t ready to download them yet.

As test (not a fix) do the warnings stop if you add --backup-test-samples=0 to your job?

Note that this just tells Duplicati to NOT perform the post-backup test. Your backup itself should run as normal, but existing backups are no longer being tested to make sure they’re still valid.


#5

Hello @JonMikelV,

Sorry for the delay, I was out of my office these last two days…

The destination I use is hubiC, an online storage solution developed by the OVH group, a French company. This solution offers a large storage space and is cheap, but it is not renowned for its upload speed which is very slow… as well as my internet connection…

Surprisingly, I have no more error message. Has hubiC services be improved? Or were the servers overloaded at that time? I’m going to wait for the next error messages and then I’ll use --backup-test-samples = 0 for testing purposes.

In the meantime, is there a way to make sure the backup is OK?

Thank you for your help.


#6

I’m using Hubic and have fails on every backup for some days.

Duplicati gives several error 503 ( server not ready). Other times Duplicate find files in remote storage that are not in the local storage. And sometimes fails trying to delete some files on remote site.

I have 2 backups to Hubic, one is a server and the other is my laptop. Both of them fails.

Hubic don’t accept new users. OVH will maintain users, but will not accept new ones. And they will not improve their infraestructure.

So, I think that Hubic is not a good place for your backups…


#7

Hi @dapobe,

You are right, hubiC will not improve their solution,because they stopped to sell it! And that’s a shame.

hubiC is a French storage with servers in France under French law which protects personal data, main reason why I subscribed.

I tried iKoula, another French storage which has little bit better upload speed but didn’t convince me and is less cheap.

I will therefore continue to use hubiC waiting for a better solution …:slightly_frowning_face:


#8

Maybe Jottacloud, a norwegian provider. But I’ve read that restores are slow ( Duplicati use 1 trhead and Jottacloud own software uses 6 threads to download data).

Another solution is Amazon S3 using an european site ( Ireland, Frankfurt, etc…). S3 is, by the way, the cheapest solution.
