Hello Philipp,
no, this client does not also host the director or storage daemon.
Once all my backups are through, I'll check with some low-level tool, if
there is any difference in read speed between those file sets (but I don't
want to skew the results by having concurring reads
on the disk).
cheers,
Erich

Hello Erich,
the only way that I can think of is that you are backing up your own storage
which reusults in a
loop. Is this possible?

Hi,
I see vastly differing backup speeds on a single machine, single partition - -
the jobs only differ
regarding FileSets (and name/description, of course):
FileSet {
Name = "Set1"
Description = "Backup Set1"
Include {
Options {
Signature = MD5 # calculate md5 checksum per file
One FS = yes # change into other filessytems
No Atime = yes
Sparse = yes
}
File = /home/user
}
Exclude {
File = /home/user/sub/directory
}
}
FileSet {
Name = "Set2"
Description = "Backup Set2"
Include {
Options {
Signature = MD5 # calculate md5 checksum per file
One FS = yes # change into other filessytems
No Atime = yes
Sparse = yes
}
File = /home/user/sub/directory
}
}
Set1 took ~2.5 days for ~6 GB and Set2 has already backed up 60 GB within the
first few hours.
Neither cpu nor io was saturated during the backup of Set1.
I suspect Set1 to have smaller, slightly compressable files and Set2 to have
larger, uncompressable
files - does this rectify this huge difference in speed or should I look for
something else?
In case it matters: This is ext4 on luks. The machine encrypts the backups (but
again: identical for
both). The os is archlinux32.
regards,
Erich
