Macrium Reflect Standard Edition v5.1.5529 - 16-1PY2-32UQ-MM3Q-WW91-JSZP-FP89QBD

 

Share:

Share name:  Backups

Comments: 

Allocation method:  Most-free

Min. free space:  45000000

Split level:  2

Included disk(s): 

Excluded disk(s): 

Export (SMB):  Export read/write

Export (NFS):

 

From my understanding of the Most-Free allocation method, the \\tower\Backups share should only map to physical disks with at list 45GB free.  However the failure log seems to indicate that the resource is not available to perform the backup.  If I run this manually aftsuccessful, I have been successful for the last 4 times that it has failed. 

 

I'm not married to performing backups this way.  If anybody could give me a better idea or help me understand how to correct this, I would be grateful.

cache drive installed?

have you asked on the macrium forum on these issues?

 

Big fan of macrium here, though only do once a week backup of the hard drive (my docs/my music etc all point to unraid) so only stuff getting backed up is the os and apps installed.

Also another tip, i also backup the flash drive once a month to my hard drive automatically.  So if it dies i got a copy of it.

I've not posted my exact problem to the Macrium forum, but my searches for similar issues point to using "free space options" on the various NAS systems used as backup targets.  Apparently Macrium is able to ask for the ultimate file size when they open a handle to the file system and I guess they expect the OS (or NAS system) to honor the filesize indicated.

 

I like the idea of backing up the flash to the local drive.  I do have a duplicate flash drive taped inside the cover of my unRaid box, but it's simple insurance in case something gets corrupted.

It failed again this morning.  There was nothing in the syslog (attached) around 4:00am that indicated any abnormal activity (although it looks like I have a SATA link?? that's unhappy back on 2/7). 

 

Am I using the "most free" allocation correctly?  Is the split level 2 causing problems?  When I rerun the task in the morning (no more that 5 hours later) everything works properly.  Maybe I need to "wake" the array up before trying.
