Backup of a Lustre file system requires special handling of extended attributes (XATTRs) which are name:value
pairs associated
permanently with files and directories. Lustre uses extended attributes to store Lustre-specific meta data features such as
file stripping. This meta data must be restored before the actual file data is placed. Bacula will automatically detect
a Lustre file system and back up file and meta data in the appropriate order for restore back to Lustre. When configuring a
Fileset that includes directories within a Lustre file system, it is important to enable the XattrSupport directive in
the Options section.
Fileset {
Name = "LustreSet"
Include {
Options {
Signature = Sha256
XattrSupport = yes
}
File = "/mnt/lustre/home/alain"
}
}
Additionally, if Access Control Lists (ACLs) are used on the Lustre file system, you can enable backup of ACLs with the AclSupport directive in the Options section in the Fileset.
Fileset {
Name = "LustreSetAcl"
Include {
Options {
Signature = Sha256
XattrSupport = yes
AclSupport = yes
}
File = "/mnt/lustre/home/alain"
}
}
