We have found that a dir (containing mostly home directories) with roughly
one and a half million files, took too much time to be backud up; it is not
a problem of backup media, also with spooling it took hours to prepare a
spool.
There's some strategy i can accomplish to reduce backup time (bacula
side; clearly we have to work also filesystem side...)?
For example, currently i have:
Options {
Signature = MD5
accurate = sm
}
if i remove signature and check only size, i can gain some performance?
Thanks.
Hello Marco,The typical way to help with this type of situation is to create several Fileset/Job pairs and then run them all concurrently. Each Job would be reading a different set of directories.
Doing something like backing user home directories that begin with [a-g], [h-m], [n-s], [t-z] in four or more different concurrent jobs.
A coup
le FileSet examples that should work in how I described:
----8<----
FileSet {
Name = Homes_A-G
Include {
Options {
signature = sha1
compression = zstd
regexdir = "/home/[a-g]"
}
Options {
exclude = yes
regexdir = "/home/.*"
}
File = /home
}
}
FileSet {
Name = Homes_H-M
Include {
Options {
signature = sha1
compression = zstd
regexdir = "/home/[h-m]"
}
Options {
exclude = yes
regexdir = "/home/.*"
}
File = /home
}
}
...and so on...
----8<----
Hope this helps!
