RN212 Backup allways full ?

RN212 Backup allways full ?

Dear all,

 

I have a ReadyNas RN212 which works just fine, and I am very happy about it 🙂

However, there is a little issue:

I do overnight backup to a remote disk over SSH (rsync over remote SSH). It works fine. The datas are correctly saved remotely. That is cool 🙂

The problem is that every night , it does a FULL backup. Can't we do an INCREMENTAL backup ? The idea is to avoir to copy all the data over and over again.

I firmware of the ReadyNAS is up-to-date (6.10.2).

 

Thank you in advance for your answers.

There is a setting for that.  Is the backup job using it?

Hello Stephen,

 

Thank you for your answer... Sorry, but I don't know where is that setting and I don't know how I can check this setting... Can you please advise ?

 

Thank you very much in advance.

It's a setting on the backup options tab - though it is worded the other way around (saying how often you want to make a full backup).

How are you determining that system isn't doing incremental backups?

Hello Stephen,

 

I tried that setting, and I tried it on 'First Time' and on 'Every week'... same result :-(.

I assume it does always do a full backup because of the time it takes (sereval hours) to proceed to the next backup...

I have one backup that contain 100GB, and it takes more than the night to complete (despite the fact that it did a backup the day before)...

 

What can I do ?

Download the full log zip file, and look at the details in the backup logs. 

 

backup_XXX.log contains a summary for all of the backup jobs XXX and that includes an indication on whether the backup job was full or not. Start and finish times are in Unix epoch time format - you can convert them to GMT using this website: https://www.epochconverter.com/

 

backup_XXX_copy.ZZZZZZZZZZ.log is a summary of the most recent backup run for job XXX.  It holds a list of the files that were backed up, along with the number of bytes that were sent and received over the network.

 

If the two NAS are in different locations, it would also be useful to know the internet upload speeds for both locations.

Hello Stephen

 

First, thank you for your support.

Second, here is an extract of the log:

---

Backup Job Type: Incremental
Protocol: rsync+ssh
Backup Source: [COMMANDES]/
Backup Destination: [remote:rsync+ssh]/gbackup.innovip.be://data/Gback-XXXXX/Online-backup/Documents/COMMANDES
Backup Start Time: Thu Jan 30 2020 1:05:30 AM
Backup Finish Time: Thu Jan 30 2020 3:41:39 PM
Backup Status: Success

---

So, it does say it does an Incremental Backup, but it takes more than 14 hours to complete... Isn't it strange ?

 

Indeed, the 2 NAS are in DIFFERENT LOCATION, but... 14 hours... seems VEEEEERRRYYY slow to me (specialy if we consider than both sides have very good internet connections)...

 

What do you think ?

And... in addition to what I said, I see the following at the end of the log:

---

sent 179,470,264,904 bytes  received 1,327,956 bytes  3,414,246.85 bytes/sec
total size is 179,421,146,439  speedup is 1.00

---
 
Thank you in advance.

Re: RN212 Backup allways full ?

Are you looking in the log zip file, to see what exactly was being backed up?  Maybe also look at a smaller share, as it might be easier to troubleshoot.

 

Note that "incremental" still means file by file backup.  The backup doesn't update parts of files - if it thinks a file has changed, it will update the entire thing.

Re: RN212 Backup allways full ?

Hello Stephen,

I look at the log file of a backup (backup log) ...

Whether it is a small backup or a big one 😞

Parts of files are NOT modified. I am still thinking it backup everything over and over again 😞

What can I do ?

😞 Help please 🙂 !

Re: RN212 Backup allways full ?

Are both NAS synchronized to an internet time server?  If the time stamps are off, the NAS may not think the files are the same.

Hello again Stephen,

 

Yes, both NAS are synchronised through an Internet Time Server, and they are exactly (to the second) at the same time....

Do you have either of the two check boxes set on the options tab of the backup job?

 

Do you mean "some of the files being backed up were NOT modified"?  

 

Or that "parts of some files were modified, but those entire files were backed up again"?  If this is what you meant, that is normal.
