Well, I dump history every day already, and inject the result into a subversion repository. I could use a flat file, but subversion allows me to retrieve diff or complete version very easily. Eventually, the problem is the same, if I need to reconstruct my FS from history, I'll have to merge every version and make sure every command is issued only once and in the correct order (no sort -u for me, then). That's not a big issue, and I guess I can design a shell script using "svn diff" to create a proper history file, but that's annoying. regards, Patrickhome | help
