The Rochen Vault backs up data daily and has restore points from the previous 30 days.
The retention policy for Rochen Vault backups is as follows –
Daily backups are stored for 7 days (giving a total of 7 restore points), then a copy is archived for 5 Sundays (giving an additional 5 restore points). The result is the ability to restore to points daily for the past 7 days, or back a total of 5 Sundays beyond that.
