Hello, Using rsync+ssh as my transfer method, I find that backuppc, when backing up a new host, transfers all files, even if specific files are already in the pool.
The docs[0] say: As BackupPC_tarExtract extracts the files from smbclient or tar, or as rsync or ftp runs, it checks each file in the backup to see if it is identical to an existing file from any previous backup of any PC. It does this without needed to write the file to disk. If the file matches an existing file, a hardlink is created to the existing file in the pool. 0. http://backuppc.sourceforge.net/faq/BackupPC.html#backuppc_operation This is in contrast to what I am experiencing. Is backuppc fetching the file into memory to compare it with the pool from there? Thinking about it, this is what needs to happen because it needs to have the file to determine its hash. But shouldn't it just need to transfer the 1st and 8th 128k chunk to determine the hashing? Or is is that hashing function only used once the whole file has been transferred? -- martin | http://madduck.net/ | http://two.sentenc.es/ for years, we have thought that a million monkeys typing at a million typewriters would eventually produce the complete works of shakespeare. today, thanks to the internet, we know this is not true. spamtraps: [email protected]
