wimlib without archive

Would it be possible to use wimlib to backup to a directory instead of an archive? Like a wim capture and win extract in one step. It would allow to benefit from wimlib's stability and functionnality to make easily browsable incremental backups from the command line.

It's possible to abuse the pipable WIM support to copy a directory:
Code: Select all
wimcapture src - --compress=none | wimapply - dest
Although, you could just use 'cp -a src dst' instead. (Or 'xcopy /e' on Windows.)

thanks. xcopy doesn't work for long path, robocopy does but doesn't respect hardlinks, making the backup much bigger than the original. Cp also doens't respect hardlinks.
I tried it in powershell and got this output:
Code: Select all
[WARNING] Creating a pipable WIM, which will be incompatible
with Microsoft's software (WIMGAPI/ImageX/DISM).
Archiving file data: 6668 bytes of 6668 bytes (100%) done

Powershell corrupts binary data; I can't do anything about it. Use cmd.exe instead.

awesome. Microsoft is making Linux more attractive every day.
> instead of | seems to work indeed in cmd. However, some strange lines are printed with it:
Code: Select all

It looks like the progress text being somehow different when pipping. But I wanted to be sure everything is looking alright from your point of view?

The output will be garbled because both commands will print their progress lines at the same time. There isn't a --quiet option yet, but you could try redirecting the output of the second command to /dev/null ("nul" in cmd.exe) I guess.

wimlib-imagex v1.12.0-BETA2 has a --quiet option now.
