The pg_wat.tar.gz contains: srap32dxr1:/data/postgresql11 # tar tzf backup-20200414-1/pg_wal.tar.gz 000000010000000C0000009D i..e. the files 000000010000000C0000009B ... 000000010000000C0000009D could be removed in wal_archive/ Correct? Or how is the long time storage of this dir? matthias -- Matthias Apitz, ✉ guru@xxxxxxxxxxx, http://www.unixarea.de/ +49-176-38902045 Public GnuPG key: http://www.unixarea.de/key.pub
