Tar incremental backup causes segmentation fault

Solution Unverified - Updated -

Environment

  • Red Hat Enterprise Linux 6.2

Issue

  • Creating incremental backup using tar fails with Segmentation fault
# mkdir test
# cd test
# tar -czf test1.tar  -g snap.log --one-file-system  /
tar: Removing leading `/' from member names
tar: Removing leading `/' from hard link targets
# tar -czf test2.tar  -g snap.log --one-file-system  /
Segmentation fault (core dumped)

Resolution

Update tar to version tar-1.23-7.el6.x86_64.rpm (available in RHEL 6.3 Beta)

Workaround

Instead of using / as the only parameter use list of directories in / as tar parameters

# tar  -czf test1.tar  -g snap.log --one-file-system /*
# tar  -czf test2.tar  -g snap.log --one-file-system /*
