Re: [BackupPC-users] Compression

3. Yes, there is certainly some confusion in client/host or host/server naming schemes :-) Actually, I could imagine that the rsync compression could be a reason for writing the custom perl version, which BackupPC use: You just don't uncompress and store the already compressed file... But I doubt

Re: [BackupPC-users] Compression

3. Sorry, I think of the machines being backed up as clients, but BackupPC does call them hosts. rsync supports compressed transfers but that's not the scheme used for storage by BackupPC. 4. You may be thinking of the tasks that check for unreferenced files and recalculate the total pool size,

Re: [BackupPC-users] Compression

Hi Robert, 1-2) This is what I would expect, I am currious if there is a way to gradually compress the files; not all at once. 3) By the host, I meant host being backed up. And I am sure, it is not used for the compression, unless compress option of rsync is used. But I guess, this is

Re: [BackupPC-users] Compression

Hi Jan, I think this is correct, but there are other experts who might chime in to correct me. 1. Migration will not result in compression of existing backups. It just allows V4 to consume the V3 pool. 2. After compression is turned on, newly backed up files will be compressed. Existing backups
