List, pgbackrest backup what all the directories and files PgBackRest will backup to RepoServer when performing backup using PgBackRest. ( Because of a limited infr ( N/W bandwidth 8Mbps between DB Server and RepoServer) .
1. I am not sure the pgbackrest command finished output message in the console is true due to the following facts. i) . My ILL - SSL VPN connection (8Mbps link) reset in between 3 to 4 times during the backup process span of 12 hours I reissued the pgbackrest backup command 3 to 4 time in this span) ii) EPAS installation dir /data/edb/as16/data showing 4.5 G only, iii) /data/edb/as16/tablespace shows 149G iv) /data Dir shows 537 G and v) /data/edb/as16/tablespace 149G for du -h command output. Kindly share your thoughts does the pgbackrest backup command ( for the first time run) performed as expected .. (Which shows in command line as finished and subsequent reissue of the same command finishes in seconds ) I can't restore back to the DB server right now to test it as it is a production server and down time granting is not immediately possible to test it ... Thank you, Krishane [root@db1 data]# pwd /data [root@db1 data]# du -h returns 537 G and [root@db1 data]# cd /data/edb/as16/data/ [root@db1 data]# pwd /data/edb/as16/data [root@db1 data]# du -h Returns 4.5G Query : 1 PgbackRest Initial full backup will copy what ? /data/edb/as16/data dir of size 4.5 G? or /data Dir of 537 G ? // I think this won't ? As my pgbackrest command issued initially finishes with following output for info command # sudo -u postgres pgbackrest --stanza=Repo --log-level-console=info backup //performed this & once it finishes I reissued this command two times again(in suspicion as I left it overnight for the backup to complete) that's why I think 2 incr backups showing here. and [root@dbtest ~]# sudo -u postgres pgbackrest info stanza: Repo status: ok cipher: aes-256-cbc db (current) wal archive min/max (16): 00000001000000830000005F/000000010000008700000019 full backup: 20240829-105625F timestamp start/stop: 2024-08-29 18:53:32+05:30 / 2024-08-29 20:24:13+05:30 wal start/stop: 000000010000008600000063 / 000000010000008600000074 database size: 146.9GB, database backup size: 146.9GB repo1: backup size: 20.6GB ### Where this 146.9 GB from ( please find the file system du -h pasted bottom of this post) incr backup: 20240829-105625F_20240830-084303I timestamp start/stop: 2024-08-30 08:43:03+05:30 / 2024-08-30 08:50:46+05:30 wal start/stop: 00000001000000870000000E / 000000010000008700000010 database size: 148GB, database backup size: 4.7GB repo1: backup size: 170.4MB backup reference list: 20240829-105625F incr backup: 20240829-105625F_20240830-090729I timestamp start/stop: 2024-08-30 09:07:29+05:30 / 2024-08-30 09:12:50+05:30 wal start/stop: 000000010000008700000015 / 000000010000008700000016 database size: 148.1GB, database backup size: 1GB repo1: backup size: 13.2MB backup reference list: 20240829-105625F, 20240829-105625F_20240830-084303I [root@dbtest ~]# For more information about the DB cluster file system Find the paste below [root@db1 data]# pwd /data [root@db1 data]# cd /data/edb/as16/data [root@db1 data]# pwd /data/edb/as16/data [root@db1 data]# du -h 20K ./pg_wal/archive_status 4.1G ./pg_wal 1.5M ./global 0 ./pg_commit_ts 0 ./pg_dynshmem 0 ./pg_notify 0 ./pg_serial 0 ./pg_snapshots 56K ./pg_subtrans 0 ./pg_twophase 3.0M ./pg_multixact/members 1.2M ./pg_multixact/offsets 4.1M ./pg_multixact 15M ./base/1 15M ./base/4 15M ./base/5 15M ./base/15355 15M ./base/42613 28M ./base/43102 0 ./base/pgsql_tmp 40K ./base/44497 100M ./base 0 ./pg_replslot 0 ./pg_tblspc 0 ./pg_stat 0 ./pg_stat_tmp 48M ./pg_xact 0 ./pg_logical/snapshots 0 ./pg_logical/mappings 4.0K ./pg_logical 280M ./log 0 ./dbms_pipe 4.5G .
