restic set tags

In a follow up to previous post https://blog.ls-al.com/restic-create-backup-and-set-tag-with-date-logic here is some code I used to set tags on old snapshots to comply with my new tagging and pruning.

# cat backup-tags-set.sh
#!/bin/bash

create_tag () {
  tag="daily"
  if [ $(date -d "$1" +%a) == "Sun" ]; then tag="weekly" ; fi
  if [ $(date -d "$1" +%d) == "01" ]; then 
   tag="monthly"
   if [ $(date -d "$1" +%b) == "Jan" ]; then
     tag="yearly"
   fi
  fi
}
create_tag
echo "backup policy: " $tag

#source /root/.restic.env
snapshotids=$(restic snapshots -c | egrep -v "ID|snapshots|--" | awk '//{print $1;}')
for snapshotid in $snapshotids
do
  snapdate=$(restic snapshots $snapshotid -c | egrep -v "ID|snapshots|--" | awk '//{print $2;}')
  create_tag $snapdate
  echo "Making a tag for: $snapshotid - $snapdate - $(date -d $snapdate +%a) - $tag"
  restic tag --set $tag $snapshotid
done

# ./backup-tags-set.sh
