Star Transactional Debian Upgrades with ZFS on Nexenta
Linked by Thom Holwerda on Fri 18th Jan 2008 14:47 UTC, submitted by erast
Sun Solaris, OpenSolaris "There is no ideal software, it always has bugs. Minor, major or security issues will always exist and modern operating systems need to deal with this fact. What if any software which user installs had a capability to rollback to previously known successful point and operation itself would take no time? What if developer or user has a tool which could checkpoint operating system and capability to revert changes in no time? This is possible if we will marry two great technologies: ZFS and Debian APT. Both technologies now part of Nexenta Operating System which is core foundation for its derivative distributions. Meet apt-clone. The tool which integrates with the NexentaCP system, keeps track of upgrade checkpoints and allows to create/destroy/edit checkpoints by request."

Windows has that since Windows 2000... Windows Vista has a fully transactional system since 1 year ago Tx-NTFS...
Welcome in late linux :-)

That's a different thing. AFAIK NTFS does not support filesystem snapshots. If you're referring to Windows Restore then you're completely off-tracks here..

And the article is about Nexenta, an OpenSolaris kernel with a Debian userland, not Linux. Casuto is obviously very confused.

I voted down your comment, as it is offtopic, beyond being trollish.

This article is neither about Windows NOR is it about Linux.

Also, the information you provide is wrong. Windows does NOT have something similiar to the presented ZFS+apt solution.

ZFS has no need for transactional support because of copy-on-write i.e. it support atomic transactions. Snapshots are free in ZFS while in Windows they will take disk space and you'll wait a while depending on how much data you are 'snapshoting'.

It seems that you havent studied what ZFS really is. You should read a bit about it? It IS truly revolutianry and the next generation file system. Why all the hype and fuzz about ZFS? There is some substance about ZFS.
