>
> Key: HBASE-28991
> URL: https://issues.apache.org/jira/browse/HBASE-28991
> Project: HBase
> Issue Type: Task
> Components: backup&restore
> Affects Versions: 2.6.0, 3.0.0-alpha-4
> Reporter: Vinayak Hegde
> Assignee: Vinayak Hegde
> Priority: Major
>
> h3. PITR Command Implementation
> h4. Current "restore" Command
> {code:java}
> hbase restore <backup_path> <backup_id>
> [-t <table_name[,table_name]>]
> [-s <backup_set_name>]
> [-q <name>]
> [-c]
> [-m <target_tables>]
> [-o] {code}
> h4. New "pitr" Command
> {code:java}
> hbase pitr
> [-t <table_name[,table_name]>]
> [-s <backup_set_name>]
> [-q <name>]
> [-c]
> [-m <target_tables>]
> [-o]
> [--to-datetime <end_time>]
> [--backup-path <backup_path>]{code}
> h4. Process for Each Table:
> # Identify the most recent backup taken *before* the {{--to-datetime}}
> timestamp and execute the {{restore}} command for that table. This will apply
> both full and incremental snapshots.
> # Determine the WAL (Write-Ahead Log) replay duration, covering logs
> generated after the last backup and before {{{}--to-datetime{}}}.
> # Invoke *WALPlayer* with the {{{}backupdir{}}}, {{{}from-time{}}}, and
> {{to-time}} parameters to perform WAL replay.
> h4. WAL Replay Details:
> * The eligible day directories will be provided as a {*}comma-separated
> list{*}.
>
> *New Option:* {{--backup-path <backup_path>}}
> This option allows users to explicitly specify the backup path, ensuring that
> eligible backups are searched in the provided location. It is particularly
> useful when backups have been manually moved to a different location, and the
> HBase system is not aware of the new path.
