apply all images as NTFS file/dir versions

Is there a way to apply a wim file in a way that the last image is the current state and all other images are accessible via the versions panel in the file/dir properties ? The times of restore points would be those of the according image creation.

Re: efficiently copying files and dirs between images

Looking forward :) More atomic functions would make wimmlib very powerfull.

Re: zstd

I used non-solid compression. It's much better for random access. I benched with official zstd command line binary from arch linux, it doesn't really offer high compression ratio indeed, even at max settings. And Wimlib's zstd version is much faster, due to the better multithreading (I know it's the...

efficiently copying files and dirs between images

Hi, is there an efficient way to copy a dir or file from one image to another inside a wim file. When I do it with wimmount (for source image) and wimmountrw (for destination image), wimlib first decompresses the whole dir or file to a staging dir, which is long and memory and IO hungry, to then res...

Re: zstd

So after trying on different set with different settings, the conclusion is that zstd is very good for very fast compression (at least an SSD is needed to see the difference as lzx is already pretty fast.) But user has to tweak the defaults. With zstd:1 and chunk-size=256K, it's 2 times faster than ...

Re: zstd

ok, tested with lots of different tweaks to chunk size and level. LZX:20 with chunk of 256 compresses as fast as zstd (using more cpu time, but the SSD is still the bottleneck in this case) and gives a file that is 27,8GB, compared to 28,5GB with ZSTD:65 with same chunk size and 28,7 with LZX:50 and...

Re: zstd

ok, it works now, I'm testing and will report asap. I definitely feel wimlib would greatly benefit from taking more freedom from the MS version as it nearly offer 100% of the functionality and thus can replace it. Only the possibility to easily navigate images by mounting or opening them in a UI is ...

Re: zstd

I also thought your optimizations would reduce the gap, but it will be interesting to compare, especially with generated dict and small files. 1) I just pulled the zstd branch, but somehow, the configure script is missing. It is in the source zip on the main doynload page, but as it's from the main ...

zstd

Hi,

would it possible to add zstd to wimlib or give some hints on how to do so? As wimlib already support parameters that are not compatible with Microsoft specs and I think most users here use the wim they generate with wimlib, I guess it will be very helpful to many people.

Regards

Re: Huge slowdown when archive size increase

Not sure how related that is, but I also tried to backup a 7TB partition with wimlib this week and got the a pretty heavy slowdown after 4TB. CPU usage from wimlib was at 2%... After 5.5TB the speed resumed and it finished pretty quickly. Would it be possible to have a kind of log to a cvs file with...
