Large PITR chunk

Hello everyone! I’m trying to understand why I have several full database backups, but only 1 large PITR chunk, documentation from percona website contains a example listing

pbm list

  2021-08-04T13: 00: 58Z [complete: 2021-08-04T13: 01: 23]

PITR <off>:
  2021-08-04T13: 01: 24 - 2021-08-05T13: 00: 11
  2021-08-06T08: 03: 10 - 2021-08-06T08: 18: 29
  2021-08-06T08: 18: 42 - 2021-08-06T08: 33: 09

where full backup named 2021-08-04T13: 00: 58Z are use as a base backup for chunk 2021-08-04T13: 01: 24 - 2021-08-05T13: 00: 11 and backup 2021-08-06T08: 02: 44Z are use as a base backup for chunk 2021-08-06T08: 03: 10 - 2021-08-06T08: 18: 29 etc…

but in my case i have 3 full backups ( which executed once a week )

I was wondering the same thing. It’s not a big chunk, if you look at the backup file then you will see multiple chunks and you can delete individual chunk. It’s just shown like that when you list it.
