NTFS question

[PSbench]

I've got a couple of questions about NTFS that I haven't found good answers for, hopefully the answers will help others as well.

Which compression formats (.zip, .rar) will maintain NTFS file properties (permissions, etc)?

What are the most popular methods for backing up NT systems that maintain NTFS file properties?

1) I believe both
2) Norton Ghost

All Permision will be retain when move/copy to the same NTFS volume (partition).

There are many third parties back-up tool that can be use with NT, but NT/Win2000 come with it own back-up ultility.

If you zip a file though, you will need to set permissions on the zip file, you probably knew that already. I don't know what happens if you unzip to another volume though. If you copy to a different partition, i'm pretty sure that you inherit the permissions of wherever you copy it too, but dont know about unzipping, probably the same. I hope I'm not wrong, haven't messed with nt administration for over a year and forget.

I've never really thought about it since I havent compressed any files with any secial perms, but I believe both formats keep the permissions as they were.

As for backup, there are plenty of utils depending on your needs.
For home backup, the one that comes with the OS is fine.

For mid range stuff, products such as Backup Exec are fine.

And for the high end, you have stuff like Legato and Veritas.

Its all up to your needs and your wallet 🙂

Neither zip nor rar keep file permissions.

When uncompressing, the files take on the permissions of the directory into which they are extracted.

I checked WinRAR, and there's an option when you create the archive to save NTFS CAL data.

I could be wrong, but only Ghost 6.5, released in August 2000, can properly *restore* to NTFS volumes. I can only assume that the previous version can create images of NTFS volumes, but can only restore to FAT16/32 volumes.
