![]() ![]() Sorry, I missed a few things here (in explanation) due to knowledge that I possess.įirst, STableBit DrivePool does do some checking. So IMHO it is much better to implement duplicates hash comparison in DrivePool itself. Another problem is that if I use 3Ñ… duplication than I have to compare 2 times (and also need a rebalance to use 3 drives)Īnother potential problem is that when i make hash comparison with my backup, corrupted data can be missed, because good "stripe" is read while comparison, but at time of backup bad "stripe" could be read. So it is impossible to use folder comparison of PoolPartxxxx with FreeFolderSync or any other tool (I need to rebalance this folder to use only 2 drives to do that). The problem is that DrivePool duplicates of my files are spread between 6 disks. Other software knows nothing about these md5 files, so when i move datafile to another place in LightRoom the md5 will stay where it was and become useless.Ĭhecksumm/hash comparison of the files with backup or synced copy is not a problem - there are tools to do that. It is good for sharing software, but not good for ordinary use. It is more like making hash(SHA/MD5) files aside protected ones. Sorry, English isn't my native language.įile Vault is potentially good product, but it solves a little bit another task. Is would be very good to implement some kind of bitwise comparison (on a folder level) to be able to find such corrupted duplicates. So the problem is that duplicated data is spread among several disks and i can't compare them with FreeFileSync or another tool. So now i run bitwise comparison before syncing. ooops it is corrupted too, because bad copy replaced good one during last syncing. The problem was that I learn about corrupted file only when i try to export photo from Lightroom. It is rare, the drives are ok (of couse they have some degradation, but will live another 5years, at least) but as far as there are a lot of files and their number constantly grows - the chance of corruption raises also. I was forced to do so because sometimes got corrupted photos (RAW). ![]() I used to make a file comparison of my data with FreeFileSync (i make backups just mirroring needed data to NAS).
