In regular expression format:


Default from CrashPlan: 
.*/iPhoto Library/iPod Photo Cache/.*
.*/Google/Chrome/Safe Browsing.*

Extra not in CrashPlan by default:
(?i).*\.(tmp|temp|cache|part|rbf|chk|dov) <-- temporary files
(?i).*\.(bac|bak|bkp|bup|back|dmp|dump|err|log|old|prv) <-- backup files
(?i).*\.(asd|wbk|xlk|bde|bdi|bdm|bmb|bom|crc|m\_p|bdb|bks|bps|mch|sol|idb|nch) <-- program specific backup/temporary files
(?i).*\.(bmk|chw|ftg|fts|gid|hhc|hhk) <-- help index files
.*/Google/Chrome/.* <-- if using Chrome Sync
(?i).*/(Google Drive|LocalGoogle)/.*
.*/(My Cubby|cubby)/.*


Default from CrashPlan:
.*/Local Settings/History/
.*/Start Menu/
.*/System Volume Information/.*
.*/Temporary Internet Files/.*
.*/Local Settings/Temp.*
.*/Application Data/Application Data.*

Extra not in CrashPlan by default:
.*/Local Settings/History/.*
.*/(Program Files|Program Files \(x86\))/.*
.*/AppData/Local/Packages/.* <- this really still needs to be figured out as per
.*/AppData/Local/Microsoft/Windows Store/.*
.*/Internet Explorer/.*


Default from CrashPlan:
/Desktop DB
/Desktop DF
.*/Network Trash Folder/.*
.*/VM Storage
/Previous Systems.*
.*/Microsoft User Data/Entourage Temp/.*
.*/iP.* Software Updates/.*
.*/Library/Application Support/SyncServices/.*
.*/Library/Mail/Envelope Index
.*/Library/Calendars/Calendar Cache
.*/iTunes/Album Artwork/Cache/.*
.*/iPhoto Library/iPod Photo Cache.*
/Users/Shared/SC Info.*
.*/Library/Saved Application State/.*

If any of my regular expressions can be simplified please fix them! – bbodenmiller Jul 3 '12 at 6:47

also look for crashplan defaults in my.service.xml. – bbodenmiller Oct 21 '12 at 23:06

Linux: Everything ending with a ~ (backups from several editors). And to "optimize" your regexps, just a short example:

Won't this result in searching for ".~" rather than "blahfile~"? – bbodenmiller Jul 3 '12 at 0:50
Ooops -- sure, you're right, that part I messed up. Intention was to shouw how to combine the regexps. But you're absolutely right: the \~ part is wrong there and must go in a separate line. – Izzy Jul 3 '12 at 6:39
