Hi @Polem ,
Please refer below prerequisites for taking the incremental backup :
1)Enable the allow_incremental_backups in the bart.cfg file
2)Password-less ssh between BART server and Master server if they are on different machine.
3)Do not enable the wal_compression parameter in bart.cfg
4)Archiving of the WAL must enabled to the BART backup catalog at <backup_path>/<server_name>/archived_wals.
Refer below steps to perform the incremental backup :
1) Take a full backup using the bart
bart BACKUP -s hr -F p --backup-name parent hr_full_1
2) Keep the bart-scanner running in background, so it will scan the wal files from archived_wals.
bart-scanner --daemon
3) Take a incremental backup
bart BACKUP -s hr -F p --parent hr_full_1 --backup-name hr_incr_1
4) Take another incremental backup
bart BACKUP -s hr -F p --parent hr_incr_1 --backup-name hr_incr_2
You can prepare a script for automating the above steps.
For detailed information, please refer document at : https://www.enterprisedb.com/docs/en/2.2/BART_Guide_2.2/EDB_Postgres_Backup_and_Recovery_Guide.1.14....
Please let us know in case of any issues/queries.
