We have planning enabling server based archiving for a very huge database (almost reaching the maximum limit of the database size). Previously we have been just compacting the database on a regular basis with command compact -c -i. What kind of compacting option -a will do after archiving? Is it reasonable to use compact -a -c -i or not to use any more those -c -i options (only just -a)? How long time archiving can take on the first time when you archive for example 1/3 of the database documents?
