Metadata was reported as not changed, but still requires being added?


#1

I upgraded windows from 7 to 10, changed IP, used saved job json, repaired base at first start, and got this after job complete every time.

and so on


#2

What OS and File System are we talking about here? So far file meta data such as ACLs are not supported on Windows so this could be related to `nix type of OS. Anything special about those files?


#3

Hello, I have similar problem - but problem started after upgrading to newest cannary
2.0.3.6_canary_2018-04-23

No errors before upgrade.
Windows 7 x64

Backup job is stuck and need to be stopped and Duplicati restarted (database in use)

Edit:

I started new backup with verbose logging to file, so I add more information if I get them

me too after upgrading


#5

@iperov and @mmiat
Did you tried downgrade to 2.0.3.5 (or 4)?
I had this problem to, but it turn out that this error can be only symptom to Canary 2.0.3.6 and slow queries · Issue #3194 · duplicati/duplicati · GitHub problem

Edit:

I have this problem after upgrading to 2.0.3.7
issue on github:


#6

I have the same issue after updating to 2.0.3.7_canary_2018-06-17, from 2.0.3.5_canary_2018-04-13.

Recreating the database doesn’t help. Backups now take hours instead of minutes.

I’m using --check-filetime-only=true on all backups if that matters.


#7

is your issue that you are getting the “Metadata was reported as not changed, but still requires being added” errors, that the backups on 2.0.3.7 are slow, or both?


#8

Both. The metadata checks are slowing the backups down to a crawl.


#9

Just as test (certainly not a solution) does adding --skip-metadata=true improve things at all?

--skip-metadata
Use this option to disable the storage of metadata, such as file timestamps. Disabling metadata storage will speed up the backup and restore operations, but does not affect file size much.
Default value: “false”

The Github post mentioned above suggests maybe the issue is related to the multi-threaded processing added in 2.0.3.6. Does setting any of the following to 0 improve things?

  • --concurrency-max-threads
  • --concurrency-block-hashers
  • --concurrency-compressors

V2.0.3.7-2.0.3.7_canary_2018-06-17 - Failed: One or more errors occurred
#10

--skip-metadata made no differences. I’ll test the concurrency stuff in the morning.

Thanks.


#11

The concurrency options didn’t make a difference either. Still getting thousands of meta-data warnings, and thus taking forever to complete backups.


#12

Thanks for doing those tests. It sounds like the bug was introduced with the multi-threading code in 2.0.3.6 but isn’t actually caused BY the multi-threading.

If reverting to 2.0.3.5 is an option for you give that a try.

Oh, and it looks like I’m not seeing any answers to @samw’s request for OS and filesystem info, can you provide that? Since I can’t replicate the problem on my Windows 10 / NTFS machine I’m assuming that’s not what you are using, but I could be wrong (maybe it’s Domain or other permission related).


#13

Using Windows 10 too…

#14

I have the same issue as ethauvin and I’m on debian:

Linux 4.9.0-6-amd64 #1 SMP Debian 4.9.88-1 (2018-04-29) x86_64 GNU/Linux
/dev/mapper/raid on /media/raid type xfs (rw,relatime,attr2,inode64,sunit=1024,swidth=2048,noquota)

A commonality between us is the use of --check-filetime-only=true


#15

I’ll try to give that a test, but I was under the impression that parameter was added as an attempt to STOP the metadata errors, is that not correct?


#16

No, I had that setting prior to the upgrade from 2.0.3.5 to 2.0.3.7. I was using it to speed up the 2.0.3.5 backups.


#17

Yeah - and there’s no need to test now because one of my backups just came up with that warning yesterday! Yay?

So this was with 2.0.3.7 on Windows 10 w/NTFS and I’m not using --check-filetime-only.

In looking at my history it seems this has happened 3 times total, all since May 11 and on two machines (both Windows 10 w/NTFS). Since I update pretty much as soon as I see an update is available I’m going to assume it started with the 2.0.3.6 version that cam out on April 23.

There were plenty of success runs between these warning runs so whatever the issue is is seems to be transient.

@kenkendk, it seems this message has a typo (“UnexpextedMetadataLookup” vs. “UnexpectedMetadataLookup”) is it worth fixing that BEFORE the surrounding issue is resolved or should it be left alone so as not to muddy the error messages?

#18

In my case, almost every single file I backup for every backup produces this warning. So my backup of 38083 files produces “38051 warning(s)”.


#19

Same here. Multiple backups (local and remotes) all having the same behaviors now.


#20

Not transient for me. Every time, every single backups.
