Having moved to Linux from a Novel Netware environment, I really missed the "Salvage" facility that Novel had. It would keep multiple copies of changed files so you could step backward through each changed version of a file till you found the last known good version.
One of the problems I've faced over the decades of trying to move people to UNIX and Linux from other systems, VMS, RSTS, and even MS-Windows is that while there are tools and facilities that do the same job, often do the job better, they do it differently, have a different name, or a different UI/Gui. Sometimes the context is different and issue the tool on the old system simply doesn't exist on UNIX/Linux because the need is not there. Sometimes this bites in a different way. A recruiter might want want someone with "Websphere" experience and not realise that means "apache" + "java" + CORBA + MQ and some connector/server stuff. Some people have a hangup about names. The thing is that Linux does have a backup facility that keeps however many copies you tell it of whatever files you tell it, if your file system supports the capability of notifying the kernel when a file is changed. Some FS won't tell the system when things change. Don't ask this of NTFS! Default is things changed when Yast/Zypper installs a new item or update so that you can roll it back, but there's no reason you can't set it up as a 'poor mans CVS'. Of course using a proper development GUI/UI rather than the manual shell/vi/cc appraiser might automate things as well. It may have many other advantages as well. One of my buzz-lines is "Context is everything" and the mechanisms built in to late-model file systems, LVM, RAID as well as SDKs might address specific contexts more suitably than traditional backup models. I've seen 'traditional' backup models which are not aligned with business needs actually disrupt business operations. If you have the hangup about names you might want to make use of the aliasing mechanisms available with Linux or write a shell wrapper for the utility called 'snapper'. Never forget, its not the backup process that counts, its the ability to restore business operations that matters. -- When you know that you're capable of dealing with whatever comes, you have the only security the world has to offer . -- Harry Browne -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
