Even if you specify exclusion in XCP, it tries to return the atime

[shirotan]

If -preserve-atime is set even when the exclusion setting is specified, it seems that the file under ~ snapshot is also being tried, and an error is output to the console.
I want to avoid errors, but is there a way?
(I think it's best to take the source as a snapshot and not use preserve-atime.)

Hello,

The -preserve-atime is to restore last accessed data on source before XCP read the file, can you provide what error are you receiving and what's the command you running trying to exclude the ~snapshot directory.

Thanks

Hello,

The error you getting is normal, since the option -preserver-atime requires write permission to set timestamps on the source file, and since the file is a snapshot which is a read only file system.  So i believe you can ignore this warning message as xcp is trying to preserve atime at source which is snapshot, at target atime is preserved. So this is not an issue.

Hello 

hmoubara

I understand that XCP cannot modify the atime in the snapshot area.
I have set "-exclude path ('* \ ~ snapshot \ *')", but I think the problem is that -preserve-atime targets it.

In the current XCP, atime modification of files in the excluded area works.
Is there no choice but to ignore any errors that occur?

[hmoubara]

Hello,

The error should just be ignore as this is not an issue. The -exclude is for the type of command being used with xcp like scan/verify/copy etc...

You can check the below KB:
