Recover deleted files across snapshots

Is there an easy way to restore all files from a specific folder across snapshots?
Thanks in advance!

I wrote a shell script to handle this

ibidani/scripts/blob/main/restore-deleted-files-restic.sh

#!/bin/bash

# define a function to list the deleted files between two snapshots
list_deleted_files() {
  restic diff "$1" "$2" | grep '^-' | awk '{print $2}'
}

# define a function to restore the deleted files between two snapshots
restore_deleted_files() {
  # get a list of deleted files
  deleted_files=$(list_deleted_files "$1" "$2")

  # if there are any deleted files, restore them
  if [ -n "$deleted_files" ]; then
    echo "Restoring deleted files from snapshot $1 to snapshot $2:"
    echo "$deleted_files"
    echo
    restic restore --target /path/to/destination/directory $deleted_files
  else
    echo "No deleted files to restore between snapshot $1 and snapshot $2"

This file has been truncated. show original

Hi @idan and welcome to the Restic community!

Tip: Restic also has the ability to output json output. This is easier to parse and gives you more information as well.

An example: I am removing a .txt file

restic diff --json 183d6f85 0aa78957
{"message_type":"change","path":"/data/blu.txt","modifier":"-"}
{"message_type":"statistics","source_snapshot":"183d6f85","target_snapshot":"0aa78957","changed_files":0,"added":{"files":0,"dirs":0,"others":0,"data_blobs":0,"tree_blobs":2,"bytes":1525},"removed":{"files":1,"dirs":0,"others":0,"data_blobs":1,"tree_blobs":2,"bytes":1943}}

This json can now be filtered with jq for example.

This way you

Hope this helps
