Vladimir Rodionov commented on HBASE-16574:
-------------------------------------------
TTL of a system table controls for how long we will keep all backup meta and
backup images (because, they can not be resolved/used without meta) in a
system. Default, 1 year, will allow to keep backup meta and backups for 1 year,
that can be too low for some customers, i.e. there are some requirements to
keep data for at least 5 years in finance and banking AFAIK.
