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

Run

# ./backup-tags-set.sh
