Hello Dears, 

i have AIX server which act as file server for invoice application that saves millions of invoices every month

the directory which contains the invoices, the directory structure is consists of such directories stands for the year/month/day structure such as dir > 2021 > 01 02 03 04 05 06 07 08 09 10 11 12  and 01 has directories for days and etc 

i configured the directory to be backed up as synthtic full and daily inc but the jobs are failing in the scan phase due to the huge number of files and folders 

i tried to create multiple subclients to minimized the scan window but still has the same issue, scan phase takes long time and fail in the end while directories other than the invoices is working normally. 

 

appreciate to enlighten me with a solution or another backup starategy that will help to fix the issue and reduce the backup time.

 

also, appreciate to advice if i increased the network agent on subclient level and enabled folder level multi-thearding and set to 30 will it be helpful? 

 

thanks in advance

Hey @Muhammad Abdullah 

 

I have a couple of questions here.

 

1. How did we arrive at below conclusion?

The jobs are failing in the scan phase due to the huge number of files and folders 

 

2. Could you please check FileScan.log on client for any errors? At the same time when scan is running, do you notice any system / kernel related errors? 

scan phase takes long time and fail in the end while directories other than the invoices is working normally

 

3. Any Job Pending Reason being logged on Commcell Console for the corresponding job?

 

4. What is the Service Pack Level on Commcell / MA / Client?

 

Thanks,

Sparsh

Hello @SparshGupta  

thank you for your reply.

1 . The jobs are failing in the scan phase due to the huge number of files and folders

  • other directories job on this server are running normally and this dir is the only one with the specific structure and the number of files. 

2 . a part of the FileScan.log

Hi @Muhammad Abdullah 

 

Could you please confirm if “/opt” on client has enough free space?

 

(No space left on device)-Failed write to [/opt/commvault/iDataAgent/jobResults/2/7355/FilterTot.cvf]

 

During Filescan phase, we generate certain files under JobResults directory which is needed during subsequent phases. But, due to low disk space, we are unable to write data to those files resulting in scan erroring out.

Hello @SparshGupta 

Yes, there are 38gb free in /opt 

i’m not sure if i did the ecuation right or what but the result was 1.22 GB,

  • backup_disk_space: 6 x 4,000,000 x (50 + 1) = 1,224,000,000 Bytes (1.22 GB)

Hey @Muhammad Abdullah 

 

Would it be possible to run another job and keep a track regarding disk space under “/opt” when scan is in progress?

 

A small script to redirect the “df -g | grep opt” output to a temp file every 5 seconds should suffice.

 

Thanks,

Sparsh

Hello @SparshGupta 

we are already have a notification when /opt exceeds 80% of total space, and it havent exceed it before. 

however, i will keep it under monitor. 

do you think that increasing network agent along with using maximum readers and enabling multi-threading set to 30 will improve the job performance?

Hello again, 

update.

i have increased the /opt dir just to eliminate the capacity issue. then erased all the job result old files and performed another job and its succeeded. 

after that  all the full or synthetic full backups still failing with the below error 

connection to the client is working.

no antivirus on the client.

/opt has 44g free space.

below is the subclient advanced setting.

any ideas?

Hi @Muhammad Abdullah ,

When you escalate, please mention the following details as well:

  • Number of files and folders present in the subclient content.
  • RAM capacity of the client machine, along with free RAM at that moment.



Thanks,
Mani

Hi @Muhammad Abdullah, hope you are well.

Have you got a fix for your issue, i have an almost similar issue, AIX File system scans for over 8 hours and completes backup in less than 5 minutes. Any ideas please.

Thanks,

Hey @Glenn Ngobeni

 

Filescan is an expensive operation. If you are backing up root, we scan the entire machine to check which files and folders qualifies for backup.

 

If it qualifies small subset of files during scan phase, backup will obviously complete much faster.

 

If you can share the job ID and FileScan.log, I can quickly check what’s happening 😀

 

Thanks,

Sparsh

Hello @Glenn Ngobeni 

im still stuck in the same issue. 

i have tried mostly everything. 

true full backups , synthetic and INC, IntelliSnap, LAN Free backup. 

all led to the same issue scan for very long time and either it success or fails due to loss of control error.

i have divided the data in to multiple subclients and it success to backup but when you try to restore it takes years to browse the data or it don't sometimes! i don't know the root cause of it, but i believe that commvault is unable to maintain scanning millions of files, the process stuck and hand after a long time of scanning then the job interrupted.

Hi @Muhammad Abdullah 

 

Can you please raise a ticket with customer support and share the ticket number?

 

We haven’t seen any issues with scan or restores or otherwise on customer site who are even backing up petabytes of data. Could be something environmental but hard to comment without proper logs.

 

Thanks,

Sparsh

Dear @SparshGupta  

i have already raised a ticket and the support advised to divide the data to multiple subclients and the backup succeeded after i made a small subclient then the support said the the issue was resolved XD

Hey @Muhammad Abdullah 

 

Good to know that your backups got working after splitting the content into multiple subclients. Hope you are taking advantage of multiple data readers for faster backups and more efficient throughput 🙂

 

But, as you mentioned the below statement, did we have any ticket for restore issue?

when you try to restore it takes years to browse the data or it don't sometimes

 

Thanks.

Good day,

 

My issue of scanning for a long time and transfer for few minutes got resolved. I had a log directory which was created out of DB normal directiories, after excluding the log directory, backup completed within 5 minutes instead of 17 Hours. 

Thanks for the support family.

@Glenn Ngobeni  Hello, 

 

could you explain what you mean by DB normal directory ? 
and are you talking about the CV log files ? 
my log files is located under /var/log/commvault/Log_Files
