Hi,
The issue is resolved after I increased the number of devices
under a filechanger.
Nevertheless, the suggestion to keep the file server and the
bacula-sd on the same host is good one.
If you are using backup to tape then yes, running a dedicated
bacula-sd on file server is a good recommendation.
Also true if the file server in question is only for the backup
volumes.
I assume a "file server" mentioned above is not a server which only
holds backup volume files but a common sense of this term like storing
user profiles, documents, production files, photos, movies, etc.
If the "file server" holds only backup volumes, then I personally do
not name it "file server" but a backup server. Exporting backup volume
files used by SD without a proper operational synchronization is not a
good idea. It does not harm your backups when exported as read-only,
but full-access...
OK. Backup server, then. The point was to move SD to the host where the
backup volume files are stored to prevent doubling the network traffic
required. If data is stored on that host as well, then care must be
taken to ensure that the storage that the volume files are written to is
isolated, physically and logically, from the storage that data is
written to.
But! If you backup to file volumes and disks mounted directly on
this file server then it is - generally - not recommended. In the
worst case scenario you can lose all your data including backups.
Be aware.
Yes. It would never be a good idea to have backup volume files and
data on the same set of physical disks.
NO, it doesn't matter if it is the same physical disk, any number of
separate devices, lvm or raid groups or just a network filesystem
mounted remotely. If it is available for writing with a standard file
io api then it exposes a huge risk! You should never do that.
best regards
