Print out the backup size when listing snapshots (enhancement) #693
Description
Output of restic version
Any.
Expected behavior
Adding an extra column to list the size of the backup (in bytes) can be very useful.
It'll help distinguish between different backups just by checking their size.
$ restic snapshots
