I have a geowebcache of for an entire country for 20 zoom level have more than 85 Laksh tiles which is saved in C drive ,I need to move the same file into another system with minimum downtime , traditional copy and paste method take more than 2 days and Re caching is also not possible , is there any way to do that using any specific tool
AFAIK, there is no tool. Provide info about your environment. If its linux, zip tilecache folder and transfer to target location with scp command. 25 gb of tiles may occupy 4.5 - 5.5 gb space if you zip it. It may take approx. 30 min - 1 hour to copy into target location & 4-5 hours to unzip, based on your network speed to transfer & system resources to unzip. be ready with all transfer & unzip work in a folder of target system and then initiate downtime. Less downtime will be taken in this way.
