Hi Alvin, If you were able to upgrade to version 1.4, it includes a checksum checker. This runs by cron job, and checks the checksums of the files are consistent with the checksums held in the database. Any inconsistencies are flagged up and sent to the administrator by email. This would ensure that the files held on each of your servers is not only identical, but is identical to the original file uploaded (in case it got corrupted before being copied to your second server).

We intend to submit content to the first server (behind the firewall) and mirror the contents to the second server via database dump/restore and assetstore copy via filesync (or rsync). My question: is there some way of ensuring data integrity or validity in copying the assetstore files? I'm sure there are other sites with a similar setup and it occurs to me that a simple file copy is prone to loss or undetected corruption. No? Anyone have any best practices they'd like to share regarding mirroring? Thanks in advance, ------------------------------------------------------------------------ - Take Surveys. Earn Cash.
