Hello,
Hello
I have configured the backup system with the
"Always-Incremental-Feature". I use the "Virtual-Full-Feature"to
archive the data.
It works perfectly!
However, I would like to use the "Virtual-Full-Feature" to archive
normal "Full-Backups". At the moment there is the problem that full
backups which are larger than 1GB take too long to archive.
A 2GB job took more than 5 hours before I quit the job.
Measures I did were to tune the "mariadb" and benchmark the read and
write speed of the different hard disks.
After these changes and tests, the 2GB job took 1 hour to archive
through "Virtual Full Feature". That's better, but still too slow.
Unfortunately, some full backups have a size of up to 30GB.
My questions would be.... How do you archive your backups for a
longer time? Are there other options than archiving via VirtualFull?
How can I make the data transfer from volume to volume faster?
Some statistics... Server is in the cloud With a dualcore of the
current generation And 8GB RAM Disk space is sufficient
To what type of device are you writing the virtual full backups to?
Disk, tape, something else?
I generally find that turning on spooling helps. Turn on "spool
attributes" to have Bareos write everything to your database at once at
the end of the job. Turn on "spool data" to have Bareos write the
output to a local disk and then flush to the output device. (The "spool
data" won't really help you if your final destination device is a local
disk.)
The "server is in the cloud" part makes me curious, generally Bareos
doesn't care much about CPU performance but is all about I/O
performance. Since we don't know anything at all about your I/O setup it
is hard to provide advice.
