Josh Elser commented on HBASE-16574: ------------------------------------ bq. No, it is not necessary. This is HBase table TTL not backup - specific TTL Gotcha. Just used when the table is created the first time -- users who want to change this would just alter the table after the fact. Good to document :) bq. Default, 1 year, will allow to keep backup meta and backups for 1 year Just making sure, the current docs and (I think) code disagree with you. They read as though it's an unlimited TTL, not one year (looking at {{BackupRestoreConstants.BACKUP_SYSTEM_TTL_DEFAULT}}). Is that the right one? > Add backup / restore feature to refguide > ---------------------------------------- > > Key: HBASE-16574 > URL: https://issues.apache.org/jira/browse/HBASE-16574 > Project: HBase > Issue Type: Improvement > Reporter: Ted Yu > Assignee: Frank Welsch > Labels: backup > Fix For: 2.0.0-beta-1 > > Attachments: B&R command-line tools and configuration (updated).pdf, > Backup-and-Restore-Apache_19Sep2016.pdf, HBASE-16574.001.patch, > HBASE-16574.002.patch, HBASE-16574.003.branch-2.patch, > hbase-book-16574.003.pdf, hbase_reference_guide.v1.pdf > > > This issue is to add backup / restore feature description to hbase refguide. > The description should cover: > scenarios where backup / restore is used > backup / restore commands and sample usage > considerations in setup -- This message was sent by Atlassian JIRA (v6.4.14#64029)
