Hi, I am new to backuppc so please apologize if this has been asked before.
I am testing backuppc for a few weeks now. Works very robust and fast. But I wonder about the number of files and directories backuppc creates in an incremental dump. I am backing up server2 with a filesystem containing about 3 million files spread over about 300,000 directories. backuppc's summary for server2 tells me Level 0: 3084565 files (470 GB), 1159994 files (60GB), 2150650 files (410GB) Level 1: 11024 files (2.8 GB), 8482 files (101 MB), 60139 files (2.7 GB) Counting the number of files on the backup-device leads to /path/to/backup/pc/server2/0: 3634406 files (including directories) /path/to/backup/pc/server2/1: 429770 files (including directories) Investigating the differences regarding the level 1 dump, I found out that the whole directory structure of the filesystem is created for the incremental dumps, independent if the dir contain files to backup or not. I think this may lead to problems regarding the number of files on the backup-device. My whole test setup running for 2 month lead to 140 million files/hardlinks/directories. Filesystem checks or removing of large parts of the backup took substantial amounts of time. Option IncrFill is not set neither global nor for the client. Is this layout really necessary? Can I avoid creating the whole dir structure? -- Regards Christoph ________________________________________________________________________ Christoph Litauer [EMAIL PROTECTED] Uni Koblenz, Computing Center, http://www.uni-koblenz.de/~litauer Postfach 201602, 56016 Koblenz Fon: +49 261 287-1311, Fax: -100 1311 PGP-Fingerprint: F39C E314 2650 650D 8092 9514 3A56 FBD8 79E3 27B2 ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
