tape backup keeping of Exchange 2010 for restore
Posted on 2012-09-18
i have come across with strange issue. i get backups of Active Directory, Sharepoint 2010, SQL 2008 and some other filesystems with HP Data Protector 6.20 to tape library.
i use LTO-3 standard. Exact issue is:
i started backup of Exchange 2010 in September 2011. i get biweekly and monthly full backups of database and daily incremental. currently i have approximately 5 full backup tapes and 3 incr tapes. so the question is: do i have to keep all the tapes or can i overwrite the tape from September 2011? in this case will i be able to restore email from October 2011 if there will be a need?
