Hi, These are two backup tools provided by CFS: star and e2scan. star (ftp://ftp.berlios.de/pub/star) is a tar like archiver, which has the capability to read and write file system extended attributes (EA) for files when the file system has an EA api.CFS patch this program to support lustre striping EA. e2scan is a program using libext2fs to find inodes with ctime or mtime newer than a given time and print out their pathname. Simple usage examples for star with lustre-support is: 1.create (backup) star -cv -lustre f=tarfile file1 file2 ... 2.extract (restore) star -xv -lustre f=tarfile /* don''t preserve osts */ star -xv -lustre -preserve-osts f=tarfile /* preserve osts */ 3. copy star -copy -lustre file1 ... directory /* don''t preserve osts */ star -copy -lustre -preserve-osts directory /* preserve osts * Simple usage example for e2scan: e2scan -u -f filename dev which will create a file named modified_pathnames include all modified file''s pathname. more detail of star and e2scan can be found from their man page.
