Dir/SD: openSUSE 11.4 (x86_64) - v5.0.3 (from rpm)
Client: Solaris 10 x86 - v5.0.3
I am having problems with an incremental backup using the accurate option.
I have two jobs for the client both of which use a script to generate a
file list of individual files (no recursion) is used. The scripts can give
different lists for each job and are specified in separate filesets. One
job is for offsite backing up with around 70GB for a full backup and one is
a local backup of around 600GB. This setup has been working happily for
months. No tapes are involved, files only.
All has been working well until suddenly I noticed the offsite backup job
was backing up over 1GB one day, the normal being around 10-20mb. Naturally
I went on the hunt for the misplaced large file, but I didn't find
anything. Looking at the logs I noticed that the jobs had backed up files
that had been there since the original full backup. Eventually I ended up
rolling back the database to check if this solved the problem, perhaps
a corruption. This seemed to work, the manually triggered offsite job ran
as expected. The next morning same problem. I eventually discovered after
rolling back the database quite a few more times, that after the other job
for that client ran (the local job) the offsite job would then go wrong and
I needed to roll back.
I have also tested creating a dummy job for that client which doesn't use
accurate and the fileset is a single file. Again running this causes the
specified behaviour. Running a job for another client doesn't cause any
problems. To clarify the jobs are still showing up as incremental, this
isn't a retention issue.
I've set the file deamon to debug and seen that for the files it's backing
up which shouldn't be backed up accurate.c reports them as "(not found)".
It seems as though the accurate list is disappearing or being altered by
running another job on the client.
Here is the job and filest definition:
#Offsite
Job {
Name = "OffsiteBackup"
Type = Backup
Level = Incremental
Client = elephant-fd
FileSet = "elephant_offsite"
Storage = File-offsite
Messages = Standard
Pool = File-offsite-pool
Priority = 10
#Bootstrap file (Use network directory)
Write Bootstrap = "/backupstore/bootstraps/%c_%d_%n_%i_%v.bsr"
#Use accurate mode
Accurate = yes
Schedule = "daily-night_inc"
}
#Offsite
FileSet {
Name = "elephant_offsite"
Include {
File = "\\|/usr/bin/perl
/export/sysadmin/configuration_files_and_scripts/bacula/bin/backup_list.pl/export/sysadmin/configuration_files_and_scripts/bacula/config/backup_list_offsite.config"
Options {
signature = MD5
#When explicitly expressing directories use
recurse=no
#Include ACL support
aclsupport=yes
#on storage daemon at the filesystem level
compression = GZIP6
#Use better accurate mode, size, times (mod, change).
Accurate = smc
}
}
}
Thanks,
Ed
