xorriso, create an iso archive from a directory which has NTFS ACLs/xattr

[Kristaps Esterliņš]

Good Day!

I am trying to create a backup archive system for our internal SAMBA shares which are joined as Active Directory members. At the moment I have succesfully created test backups using the joliet extension. The only issue left is that I cannot store or save the NTFS ACLs or xattrs from the source files and folders.

Below is the command I issue to create a test backup:

xorriso -joliet on \

-compliance joliet_long_names \ 

-compliance joliet_long_paths \ 

-abort_on FATAL \ 

-for_backup \ 

-disk_dev_ino on \

-dev /srv/samba/service/folder/service-13.09.2022.iso \ 

-volid SERVICE_13092022 \ 

-update_r service-13-09-2022/service/folder1 /folder1 \ 

-commit -toc -check_md5 FAILURE --

Snippet of the output:

...

libisofs: FAILURE : Error with reading ACL or xattr from local file: '/srv/backup/samba/service/service-13-09-2022/service/folder1/garantiju veidi.pdf'

xorriso : UPDATE : Adjusted attributes of '/folder1/garantiju veidi.pdf'

libisofs: FAILURE : Error with reading ACL or xattr from local file: '/srv/backup/samba/service/service-13-09-2022/service/folder1/Pārstāvniecības.pdf'

xorriso : UPDATE : Adjusted attributes of '/folder1/Pārstāvniecības.pdf'

Differences detected and updated. (runtime 1.1 s)

xorriso : NOTE : Tolerated problem event of severity 'FAILURE'

Thanks!

Ar cieņu, Best regards, Mit freundlichen Grüssen,
