How long do your backups take? Are you able to perform mid day backups?

asked on January 22, 2016

Currently we have a ~750gb Volume (auto rolled over into 157 5gb sub volumes; Images001, Images002, etc).  The backup job is split up into backing up volumes 1-25, 26-50, and so on.

Currently the weekly full backup takes about 13 hours to complete and the nightly incremental backup takes 1 hour 45 minutes to complete.

Average number of documents being imported into Laserfiche is between 3,000-6,000 with a net gain of only about 700mb-1gb of data per weekday.

I think these backup times can be improved but I wanted to get a feel for how long other similarly sized backups are taking to get some perspective.  Our goal is to be able to have at least 1 mid day backup without any noticeable service outage.

I was hoping the community could share some of their backup experience with me and answer a few of questions?

1. How large is your volume(s)?

2. How long does your full backup take (disk to disk, we are not using tape)?

3.  How long do your incremental backups take?

4.  Are you creating multiple backups during the day and if so how are you accomplishing this with minimal if any downtime?


Also, our current backup solution is an application called CommVault which is managed by one of our vendors so I have very little technical information on it.

Thank you.

old post I know. backup is slow for images. the TIFF files really cannot be compressed much.

we use LTO tapes. back when we had LTO3, LTO3 could take days.

LTO6 is faster but can take over 24  hours.

our typical volume size is ~40-50 GB

even robocopy a volume over network is slow.

it is a lot of data.
