How to make shadow copies (Samba 4)?

Question

linux

All the best.
Tell me how to make automatic shadow copies in Saba 4?
There is a plugin \ module for Samba 4 called shadow_copy2 but as I understand it, it makes copies manually. And how to do it automatically when changing files (a complete analogue of windows shadow copies)

Answer 1

Shadow copies in Windows are made on a schedule, not on file changes.
The closest analogue of shadow copies is very well implemented in the ZFS file system. I make snapshots every hour and once a day, I keep the first week, and the second half a year. this is enough for my purposes. You can do it more often. You can get a list of different files. Many things are possible...

Answer 2

Shadow copies in Windows have been made according to a schedule all their lives, and not according to file events.
To emulate this functionality, you can use, for example, git.
To create a copy based on file events, you can cross git with incron - serverfault.com/questions/238111/automatic-file-re...
