Snap Shot / Save System State.
« on: August 08, 2025, 11:42:39 am »
Mostly I use a VM to test with, that way, I can snapshot to my hearts content, before trying something, like an install, that might change multiple files, in multiple locations.

What is my best bet for doing that on real iron? Wasn't one of the selling points of JFS snapshots?

Once I had a big problem with VBOX snapshots. As one of the old snapshot files got damaged I couldn't go back or transfere to another machine or... Since then I don't use snapshots anymore. Never again. YMMV.

No we have no file system snapshots. zip -rS9# ... (replace # with the proper switch for symlinks, sorry don't know offhand). Or rar -x...  or rsync (we have luckybackup!).

System drive is usually small with OS/2. 1-2GB. So zip is a perfect solution for me. For big data drives I use rar scripts which splits files if the go beyond 2GB but rar is much slower than zip. rsyncing to network attached storage or usb works too. USB disks formated with JFS are not that slow.

On my sytems there are at least 2 working versions of OS/2 - ArcaOS installed. Although you can zip the system drive while running and it works (you only miss the worplace ini file changes since last reboot) I prefere backup from the other partition.
