I recently moved my backuppc server from a Linux/Intel platform to Ubuntu 9.04 on a SheevaPlug with an ARM processor. Although backuppc is working fine in terms of the files themselves, data volumes are dramatically higher than before. Further investigation suggests that <a href=File://:RsyncP>File::RsyncP</a> is reporting a high percentage of block mismatches even though the source and target files were identically. The rsync command does not show these symptoms. I have created a small Perl script that calls <a href=File://:RsyncP>File::RsyncP</a> to copy files from one directory to another on the same system. Test data are three log files and three modules, each about 3MB in size. On the Linux/Intel system: * first test: Remote[2]: total: matches=0 hash_hits=0 false_alarms=0 data=17227776 * subsequent tests: Remote[2]: total: matches=60027 hash_hits=60027 false_alarms=0 data=0 On the Linux/ARM system: * first test: Remote[2]: total: matches=0 hash_hits=0 false_alarms=0 data=17227776 * subsequent tests: Remote[2]: total: matches=33300 hash_hits=1095771 false_alarms=0 data=7537086 On both systems, rsync is version 3.0.5 and <a href=File://RsycnP>File:RsycnP</a> is 0.68. The problem is easily reproducible and I can generate verbose log output. I have reported the issue to Craig Barratt, the <a href=File://:RsyncP>File::RsyncP</a> author, and am waiting for a response. Any help in getting this resolved would be greatly appreciated! Due to recent bandwidth caps, I have had to drastically limit the number of full backups. Thanks, Norbert
